As aquarium fish
Demand a very large aquarium when fully grown
This species needs a very large aquarium when fully grown.
Exactly how big the aquarium should be is hard to say, but the size of this species is such, that it cannot normally be kept in a home aquarium.
This species grows very quickly if fed well.
Threat to fish and crustaceans
This species eats all kinds of fish, shrimps, crabs etc. which are of suitable size.
This species eats a great deal and demands an aquarium that can tolerate such a heavy load.
Requires a varied diet
This species must be fed with an appropriately varied diet.
Requires plenty of space for swimming.
This species revels in swimming and requires an aquarium with ample space.
This species can change gender from female to male.
When a male is needed, a female changes sex and takes on the role.
This species needs good hiding places, for example, between live rocks.
Number of fish
This species can live with many of its own kind, when provided with enough space.
Can be aggressive
This species can be aggressive when kept together with fish that are very similar, or if they are not provided with adequate space.
These fish are blue with yellow fins when young and become grey with black spots when fully grown.
Family description (Serranidae)
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.
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.
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
See the description of the individual genera below.
