Members of the subfamily
Anthiinae (Fancy Basses) are known by many common names around
the world. Labels include: wreckfish, reeffish, goldies, seaperch,
swallowtails, fancy basslets, and jewelfish - just to name
more than a few. The group en toto (the summation,
not the band) is represented by more than a half dozen genera.
Marine aquarists often collectively refer to them all, though,
as "Anthias."

Basses, yet many of these beauties are still difficult
to keep successfully for a full lifespan in typical
community aquariums. Photo by Robert Fenner.

There are around 200 described species of Anthiinae, all
of which are believed to be hermaphrodites. They are born
"unsexed," then become females and may eventually
develop into males (protogeny) when given the proper cues.
Most Anthias display physical gender specific body shape and/or
color differences.
|
Anthiines are examples of synchronous protogynous hermaphrodites.
They are born with an undifferentiated gender, later
turn into females, and then can become males when provided
with the right cues. Pictured here, a Pseudanthias
squamipinnis is in an intermediate stage between
female and male. Keep only one male per tank, and feed
small, frequent portions of food (2-3 times daily).

This sub-family also boasts some of the
most beautiful and oft-photographed fishes in the world. They
are living rainbows of bright colors! Most tend to be peaceful
towards other fishes - except their own kind - and that can
be a double-edged sword in a home-sized aquarium. It's a challenging
obstacle to overcome
too passive to fight for space
and food with other fishes, but more than willing to attack
their own kind. Yikes! Unfortunately, the more aggressive
Anthiines tend to be the hardier species. This speaks to the
dynamics of behavior among successful (assertive) fishes at
large in typical marine aquariums.
Captive Care
The better "Anthias" are
active, if not outright aggressive, in feeding and establishing
territories among other popular aquarium fishes such as damsels,
tangs and wrasses. More passive Anthiines will simply be intimidated
by the very activity of other fishes, and can slowly waste
away without enduring even a single nip or threat of aggression.
Fishes in the subfamily Anthiinae run the gamut of behavior
and aquarium suitability. Please choose your fishes wisely
by researching their species-specific needs, history and likely
behavior.

Even with the best species and specimens, it is still critically
important to isolate all new fishes in a quarantine tank (QT)
for several weeks (4 - 8 weeks, ideally). Look back at past
articles and archives for details on the many benefits
of strict quarantine. But do not fail to practice it, even
if only to establish a hearty feeding response in newly acquired
fishes. Athiines are categorically poor shippers with higher
rates of mortality and morbidity than other common imports.
Some otherwise healthy (on arrival) specimens will be pummeled
or killed if thrown directly into a tank of established fishes.
They truly do not fare well if forced to "hit the ground
running." Quarantine tank protocol is mandatory with
all Anthiines, in my opinion.
In hobby literature, the long-touted lore of Anthias needing
to be kept in groups is a bit in error. It's true that many
live in very large shoals or schools in the wild, sometimes
numbering in the thousands. But in specific groups and harems,
there is a decided pecking order and often considerable intraspecific
aggression. With their natural territories consisting of many
square meters in the wild, the compression of a harem into
a home aquarium results in quite an abnormal situation, regardless
of the size of the display (short of public-aquarium sized
displays). Weaker or more passive individuals get singled
out and harassed quickly, but they cannot escape far enough
away to quell the aggressor, as they can in the wild. Thus,
such practical realities make us reconsider what it will take
to keep (or not keep) Anthiines captively.
Below, we offer a compatibility chart to serve as a guide
for mixing Anthiines in aquaria with other popular reef fishes.
It's proffered, of course, with the fair warning that it is
only a general guide. With fishes that are often as sensitive
and easily intimidated as Anthiines, common compromises to
aquarium husbandry like overstocking or inadequate places
for retreat can make a precarious mix even worse. Furthermore,
I'm pretty sure that reef fishes have not read this chart
to know how they "should" behave. Thus, close observation
and the use of an isolation tank if needed are crucial. Anthiines
are especially worthy, if not needy, of being "feature"
fishes to a display where all other choices (new species and
total bioload) revolve around them.

Note: While many of the fish listed
are good tank mates for Anthiines,
you should research each fish individually before adding it
to your aquarium. Some of the mentioned fish are better left
in the ocean or for advanced aquarists.
Give Anthias very large aquariums (at least a couple hundred
gallons) to allow them a better chance of surviving a full
lifespan. It is difficult to give a rule of thumb on stocking
densities for the dozens of species encountered in the aquarium
trade, but I'll suggest a rough guideline of one "Anthias"
per 75 gallons (285 liters) of water. I strongly encourage
aquarists unable or unwilling to dedicate such space to consider
keeping a single specimen of one of the hardier varieties.
The Sunburst Anthias, Serranocirrhitus latus, are among
the smallest, best and hardiest Anthiinae for aquarium use
- provided they are given cover for protection from aggressive
tankmates or excessive light.
|
Serranocirrhitus latus (Watanabe, 1949), is known
variously as the Sunburst, Fathead or Hawkfish Anthias
and can attain a surprisingly large adult size of 5"
(12.5 cm). They are shy but gorgeous, and hardy in captivity.

Feeding
Feeding is another
great challenge with Anthiines. The main obstacle has been
that many feed almost constantly on zooplankton in the wild.
It is difficult, if even possible, to replicate in home aquaria
the nature and frequency of the matter they feed upon in the
wild. The advent of refugium methodologies has markedly improved
the success of keeping many challenging fishes like Anthias.
And the state of the hobby has evolved far beyond the dark,
early days of keeping refugia with weak water flow and Caulerpa,
to a place where aquarists now commonly construct dozens of
very different styles of refugia to cultivate very specific
types of microorganisms. Some of these styles are being referred
to as "plankton reactors," which should clarify
their purpose. Please refer to some of the fabulous threads
on refugiums and their construction in the Reef Central
forums,
and consider my thorough coverage of the topic in "Reef
Invertebrates" (co-authored with Robert Fenner).
Plainly stated, though, a staggeringly simple plankton-generating
refugium can be constructed as follows. Take an empty aquarium
or water-holding vessel (plastic shoebox, food storage container
whatever!) and tap it inline to the system. It can be upstream
from the display (fed with pumped water that overflows back
down), or downstream from the display (catching water before
or after the sump pump, and before the topside display return).
In this empty, water-filled vessel, string a series of coarse
filter pads (such as Supreme brand "Pond Master"
rigid prefilter inserts, cut to size) like clothes drying
on a line. A bit of strong fishing line will do well here.
The thick pads are to be slightly smaller than the height
and width of the water column in the tank. And, they should
be given space between each pad. This will allow strong water
flow through the aquarium and all around the pads. That's
all! No substrate; no lights needed. You simply have a dim
or dark refugium filled with coarse media suspended off the
bare bottom on a string, being given a strong water flow and
a food source (raw overflow water and/or supplemental feeding).
It's not rocket surgery
errrr, rocket science, I mean.
It's just a dense matrix with good water flow and a food source
for amphipods and other microcrustaceans to grow free from
predation. A verifiable pod disco! Many will overflow each
day and be an incomparable natural food source (and this productive
refugium cost only a few tens of dollars, at most, to build).
There is also good cause to make an argument
for timed or continuous food drips for Anthiines. Freshly
hatched baby brine shrimp, live rotifers or (best of all,
perhaps) copepods, can be loaded into a regulated drip line
(like an intravenous drip or kalkwasser drip system) daily
and be slowly bled into the display for natural and continuous
feeding opportunities. Maintaining live food cultures is not
difficult, but it can be quite tedious. Thankfully, live bottled
copepods can be purchased online from several sources.
|
Live food such as small fishes or shrimps (i.e., eurohaline
Palaemonid "ghost" feeder shrimp) are excellent
vehicles for carrying nutritious prepared foods via
gut-loading into Anthiines. The antennae hanging out
of this fish's mouth reminds us that shrimp are indeed
taken, and the definition of "reef-safe" is
subjective! Photo courtesy of Keith Berkelhamer (reefbum).
|
The better Anthias species also can learn to accept thawed
fresh-frozen foods; some will even take them readily and early
after collection. Mysid shrimp are a real a boon to keeping
Anthiines, being well received and quite nutritious. Fine
krill (pacifica plankton) is also an excellent foodstuff.
A suspension of meaty prey is usually a good choice for first
foods. The commercial slurry of freshwater Daphnia,
"Sweetwater Plankton," has also been an outstanding
appetite stimulant for new and finicky Anthias. The addition
(soaked) of vitamin B12 with all foods
has been shown to be quite stimulating to fishes' appetites
as well. And a really novel and nutritious food item is fish
eggs! Do consider how very natural it is for reef fishes like
Anthiines to eat eggs and larvae among plankton. Hobbyists
can buy nutritious, fresh fish eggs from a grocery store (in
the freezer) that offers Asian and International products,
such as sushi supplies. "Flying fish eggs" are an
inexpensive and common staple that sushi fans enjoy; fish
eggs make fabulous food for many reef fishes. Some pet stores
also offer frozen grouper roe, packaged to feed to pet fishes
and corals. Be resourceful to procure a nutritious and varied
diet for the finicky Anthiinae you might keep.
Alas, even with the best methods (QT tank use and B12
supplements to the food) and a most careful specimen selection,
some new or stressed Anthias won't eat at first and may require
temptation with live prey. Aside from the old standby, live
adult brine shrimp, it's amazing to see how readily Anthiines
will eat baby guppies and other small fishes! While such freshwater
fishes themselves are nutritionally inferior, and would be
a poor choice of food in the long term, they can be found
readily at most aquarium stores as feeder fish. Palaemonetes-type
ghost or grass shrimp are also excellent live food offerings.
These items are useful vehicles to carry nutrition into your
fishes; all such live foods should be "gut-loaded"
(stuffed full of dense and nutritious matter, such as flake
and pellet foods, vitamins, etc.) before being offered.
And for all of the challenges and concerns you might have
with needing "buffets" of frozen foods and laboratories
full of live food cultures, you can rest assured that plenty
of Anthiines will simply eat dry, prepared foods. Some of
my favorite feeds presently include Pablo Tepoot's "New
Life Spectrum" series, the Boyd Enterprises Vita-Chem
soaked products, and Argent Laboratories Cyclop-eeze.
There are, of course, many other high quality feeds on the
market for aquarium fishes. Look for crustacean based food
containing significant levels of protein.
Unfortunately, there is the occasional, outspoken aquarist,
preaching to anybody that will listen, that he is keeping
a herd of Anthias in a 55-gallon tank and feeding them cheese
doodles and beer nuts, or some other ridiculously convenient
food (brine shrimp fits this description, in all seriousness
a hollow food). The reality is that such fishes are the exception
and not the rule, and usually have not been in the display
for more than a year, if even six months. They are not likely
to survive a full lifespan either. Indeed, there will always
be exceptional fishes that have not "read the same books
we have" to know "how they should behave, or what
they should eat." That doesn't make it right to encourage
other aquarists to take a very big chance on getting a fish
that will do the same.
If you like saving more, you should browse
Lidl Special Buys! More often than not, the purchased
fish merely becomes a statistic within months. Also note that
the problem with many delicate fishes is not that they won't
eat prepared foods, but rather that they won't survive
(due to nutritional deficiencies).
A sampling of distinguished species is provided below. Please
use these comments and all other available resources for due
perspective before buying any Anthiines. Under the best circumstances,
Athiines are challenging. Make a thoughtful and considerate
choice when shopping for the best species for your display.
Pseudanthias bartlettorum (Randall &
Lubbock, 1981), Bartlett's Anthias of the Western
Pacific are among the hardiest Anthias for keeping
singly. Growing to a modest 3.5" (~9
cm.), these shallow water Anthias are unfortunately
aggressive towards others of their kind and require
so many females per male that few home aquariums
are large enough to house a group. Males are mostly
pink while females exhibit varying degrees of
yellow backs with pink bellies. Photo by Anthony
Calfo.

Pseudanthias bicolor (Randall, 1979), the
Bicolor Anthias, is a deeper water species from
the Indo-Pacific. Imports to the U.S. mainland
come from Hawaii. With growth to about 5"
(12.5 cm), they are hardy if acclimated carefully
to bright aquarium lights and active tankmates.
Bicolors are more tolerant of their own kind than
other Anthias and are candidates for large (200+
gallon/<760 liter) deepwater reef displays.
Males are distinguished by yellow-tipped filaments
on their extended dorsal spines. Photo courtesy

|
Pseudanthias bimaculatus (Smith, 1955),
the Twinspot Anthias, are stunningly beautiful
but by far one of the most difficult Anthias species
to keep successfully. Please consider this species
only if you are willing to set up a species-specific
aquarium. They need tremendous space, passive
tankmates, adequate places to hide, special attention
to feeding (live food may be required) and superb
water quality. It really is best for most hobbyists
to admire this fish from afar and select another
pretty, but hardier, Anthiinae for aquarium use.

Pseudanthias evansi (Smith, 1954), the
Yellowback Anthias (aka Evan's Anthias), of the
Indian Ocean, is an attractive but very challenging
aquarium species. They naturally occur in large
groups and do not acclimate well to home-sized
aquaria and captive diets. I do not recommend
the casual keeping of this fish by hobbyists.

Pseudanthias lori (Lubbock & Randall,
1976), Lori's Anthias (aka Tiger Queen Anthias),
is a fairly regular import from the Philippines
and elsewhere in the Indo-Pacific. With growth
to about 5" (12.5 cm.) they are regarded
as one of the best behaved Anthias for stocking
in small harems in aquaria. Although not especially
hardy, they can flourish in a very quiet tank
with peaceful tankmates, but please do not underestimate
their passive nature. Subdued lighting and reduced
foot traffic around the tank will be necessary,
at least at first, with new arrivals. Both males
and females wear the attractive "tiger stripes"
down their back, with females being decidedly
less vibrant. Photo by Anthony Calfo.

|
Pseudanthias ventralis (Randall, 1979),
the Longfin Anthias, is a small species (3"/7.5
cm) found in very deep water (not uncommonly at
300 ft!). They are very poor shippers and require
dim illumination, at least at first. Although
males can be aggressive towards one another, the
species is exceedingly passive overall. Protection
from even slightly active or aggressive community
fish is crucial. Large copepod generating refugiums
and offerings of fish eggs will be helpful to
support them. Feed small portions frequently (2-3
times daily, minimum). For advanced aquarists
and specialists only. Photo courtesy of Greg Rothschild
(gregr).
|
Pseudanthia olivaceus (Randall & McCosker,
1982) is sometimes called the Olive or Green Anthias.
They are one of the hardiest and very best Anthias
for aquarium life. They are active swimmers and
aggressive feeders requiring very large displays
(over 200 gallons, ideally). Keep only one male
per tank. The species is often imported through
Hawaiian suppliers from Christmas Island. Photo

Pseudanthias pleurotaenia (Bleeker, 1857),
the Square-Spot Fairy Anthias (aka Squareback
Anthias), is one of the most recognizable members
of this family to aquarists. Occurring throughout
much of the Pacific, they are frequent imports
from Indonesia and the Philippines. Although they
are reasonably hardy and will learn to accept
a wide range of prepared foods, most get a rough
start in captivity when thrown into brightly illuminated
dealer displays and home aquariums. Expect them
to be very shy at first and perhaps require live
food to begin feeding (gut-loaded guppies or similar
substitute work well for this). The sexes are
distinctly dimorphic with females in a fairly
uniform gold-yellow color and males displaying
a stark pink square patch on the flanks. They
grow large (8"/20 cm) and are aggressive
toward each other and other fishes - keep singly
in most cases. Pictured here: male (pink) and
female (yellow). Photos by Anthony Calfo.
|
Paranthias colonus (Valenciennes, 1846),
the Pacific Creole-fish. This fancy bass bears
a resemblance to its Anthiinae relatives and does
feed similarly on tiny zooplankton (principally
copepods, but also eggs and larvae). Their adult
size, however, runs up to a whopping 14"
(35 cm). Juveniles and sub-adults, with Atlantic
kin P. furcifer in kind, occasionally enter
the aquarium trade, but are more commonly used
as bait in local fisheries. They are hardy but
can be surly and require very large displays with
durable tankmates. Keep singly in home aquariums
and feed them several times daily with a variety
of crustaceous fare. Juvenile (top) and adult
(below) pictured here. Photos by Anthony Calfo.
