Food

Mostly
  • Larger crustaceans (Shrimp, crabs...)

  • 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.

Requires a varied diet

This species must be fed with an appropriately varied diet.

Looses colour in the aquarium

In the aquarium the colour of this species can become matte.

Food with plenty of pigment and generally a varied diet of high quality can help alleviate colour loss.

Hermaphroditic

This species can change gender from female to male.

When a male is needed, a female changes sex and takes on the role.

Bred in captivity

This species can be bred in captivity, one can therefore consider asking your local fish store for a captive bred specimen.

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.

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.

Family description (Pseudochromidae)

Dottybacks (Pseudochromidae) are often very colourful, rather hardy and relatively small, typically under 4 inch (10 cm). These fish can be distinguished from other fish by looking at the shape of the eye, see for example the picture of this: Labracinus cyclophthalmus.

They can be quite aggressive towards other fish, if they are kept together with more docile species or if there is not enough space. They are especially aggressive towards fish that resemble themselves or Wrasses, as in the wild, Wrasses will go after their eggs.

If their aggressive behaviour is dealt with, they can be suitable to smaller aquaria. Their aggressive behaivour can be remedied by keeping them together with other aggressive or larger species as for example: Hawkfish, Surgeonfish, Rabbitfish, Angelfish, Triggerfish, Clown/ Damselfish or Pufferfish.

Dottybacks will compete for food with other fish which eat zooplankton off the rocks. Mandarinfish and similar species can find it difficult to get enough food if kept together with Dottybacks.
One could consider the Gramma species, if one wishes a similar fish which is more peaceful.
