Food

Mostly
  • Larger crustaceans (Shrimp, crabs...)
Recommended
  • Zooplankton (Cyclops, pods...)
  • Small crustaceans (Krill, mysis, artemia...)

Jumps out of open aquaria

This species is known to jump out of open aquaria.

Can be a threat towards small crustaceans

This species can be a threat towards small crustaceans, e.g. small shrimp.

Low light conditions

This species thrives best in an aquarium with dimmed lighting.

Requires a varied diet

This species must be fed with an appropriately varied diet.

Likes to hide at first

These fish may well hide themselves for a while, whilst getting acclimatized.

Do not disturb the fish while acclimating because it will prolong the process.

Secretive

A very secretive species which hides between the rocks.
When it feels at home in the aquarium it will appear more, but is still not as active in the water column as most of the other fish.

Docile

This species is very shy and docile, so one should be careful when keeping it with more aggressive fish.

Hiding places

This species needs good hiding places, for example, between live rocks.

Can coexist as a pair

They can live as a pair provided they are introduced simultaneously.

Genus description (Liopropoma)

Of the Seranidae family, the Reef Basslets (Liopropoma) contain some of the smallest species. Because of their size, they are eminently suitable to smaller aquaria.
They are normally very shy and therefore are best placed in a tank with very peaceful fish, or as an single species in i.e. a nano aquarium.

As these fish live in deep water, they can be encouraged to be more forward by dimming the lighting.

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.

Anthias (Anthiinae)
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, P. bicolor, P. dispar, P. huchtii and P. squamipinnis.

Anthias include among others the following genera: Anthias, Luzonichthys, Nemanthias, Odontanthias, Pseudanthias, Sacura and Serranocirrhitus

Liopropomatinae
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.

Grouper (Epinephelinae)
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

Soapfishes (Grammistinae)
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

Serraninae
The most common genera in captivity is Dwarf Seabasses (Serranus) and Hamlets (Hypoplectrus).

See the description of the individual genera below.
