Zooplankton (Cyclops, pods...)
Small crustaceans (Krill, mysis, artemia...)
This species is known to jump out of open aquaria.
It is recommended that this species be kept by experienced aquarists as it requires specialized food for its continual survival.
This species must be fed with an appropriately varied diet.
This species is very sensitive during transportation and acclimatizing into the aquarium.
This fish requires feeding several times a day, especially when newly added.
When the fish can find its natural food in the aquarium it requires less frequent feeding.
In the beginning these fish can have problems eating frozen foods.
Food like Cyclops and Artemia is a good start when the fish are first introduced into the aquarium.
They will however over time learn to eat fish flakes.
Anthias can reside in a group with one male and multiple females if the aquarium is large enough, however, some of the group maywell die, if one buys too many.
If there is a lack of space, it will be the fish lowest in the hierarchy that will die, due to stress and lack of food.
It is best to have only one or a couple in smaller aquariums.
If one wises to have a shoal, it would be wise to keep 8 or more, so that potential aggression will be taken out on multiple specimens.
When a larger number is kept, they will require more space than indicated above.
This species needs good hiding places, for example, between live rocks.
This species is very shy and docile, so one should be careful when keeping it with more aggressive fish.
This species can change gender from female to male.
When a male is needed, a female changes sex and takes on the role.
The Sea Bass family (Serranidae) spans a broad spectrum with regards to how suitable they are to aquaria, as some are best suited to specialist or larger aquaria, while other are often seen in reef aquaria.
Below are described the five subfamilies one sees most often in aquaria. There are however other species one can also keep under the right circumstances, but these are for the most, large predatory fish.
The Anthias species spans over many different genera, but the most common is the Pseudanthias genus. They mostly have an attractive orange or pink shade.
They are generally all reef safe and peaceful.
There is however a large difference to their food requirements, some species demand constant feeding, whereas others can get used to being fed once a day.
The easiest species are the following: P. bartelettorum, Anthias, Luzonichthys, Nemanthias, Odontanthias, Pseudanthias, Sacura and Serranocirrhitus
This subfamily encompasses some of the smallest fish in the Serranidae family, they can be very colourful but shy. The Liopropoma genus encompasses many species which are suitable for aquaria, however they normally thrive best in a very peaceful- or nano aquarium.
These fish grow typically too large for most home aquaria. There are however some species that do lend themselves to the slightly bigger domestic aquarium. Several of the species look very impressive and often have a interesting personality, and they often recognize the aquarist and will become tame over time.
Groupers are predatory fish and eat everything they can swallow; fish, crabs, shrimps and sometimes other invertebrates. Like most large predatory fish they excrete a lot of nutrients to the water, so one therefore needs a good filter system.
Groupers include among others the following genera: Aethaloperca, Cephalopholis, Chromileptes, Epinephelus, Paranthias and Pogonoperca
These fish are like the Groupers predatory fish, but they do not typically, grow so large. They are relatively hardy, but some of the species demand a thorough preperation if one wants to be successful.
Soapfishes are generally very shy and will often hide under an overhang during the day, and hunt at night.
Soapfishes include among others the genera: Grammistes
The most common genera in captivity is Dwarf Seabasses (Serranus) and Hamlets (Hypoplectrus).
See the description of the individual genera below.

"Minimum volume" indicates the size of the tank needed to house this species under optimal conditions.
This is based on a medium size animal, which you want to keep for several years.
It might be possible to keep smaller specimens for a limited period in a smaller tank. A larger tank might be needed for fully-grown specimens.
"Hardiness" indicates how resistant this species is to disease and how well i tolerates bad conditions in general.
Some species doesn't handle transportation very well, but that doesn't mean that the species isn't hardy under the right conditions.
In this case, a "normal" aquarium is a reef aquarium with mixed corals or a fish only aquarium with an approximately salinity of 1.026 (sg) and a temperature close to 26°C.
Species requiring more than a 4000-liter tank are considered not suitable for home aquarium.
Special aquariums may cover tanks with low salinity, sub-tropical temperature, deep sand bed, sea grass etc.
Always reef safe: No sources indicate that this species will harm corals or other invertebrates.
Often reef safe: Only a few aquarists has reported problems keeping this species with corals and other invertebrates.
Reef safe with caution: This species may be a threat to some types of invertebrates.
Reef safe with luck: Most specimens will harm corals and/or other invertebrates, but you might be lucky.
Not reef safe: This species is a threat to most corals and/or other invertebrates.
