[edit] Other Scientific Names

Chromodoris bullocki

[edit] Origin

They are found on reefs across the Indo-Pacific, from China to Queensland.

[edit] Sexing

Nudibranchs are hermaphroditic, however they do not fertilise themselves when breeding and will pair up, with both individuals then laying eggs.

[edit] Tank compatibility

Not recommended for keeping in captivity due to their sensitivity.

[edit] Diet

Extremely fussy eaters, Dorids mainly prey on bryozoans and sponges.

[edit] Environment Specifics

Very delicate to changes in their environment. Requires an SG of 1.023-1.025.

[edit] Behaviour

Constantly on the prowl for food, they are a form of sea slug therefore move quite slowly and can be a target for boisterous fish.

[edit] Identification

Doridoidea have a broad flat foot, a fleshy mantle and a circle of gills on the posterior of the nudibranch. They range in colour from pale lavender to rich purple with a thin white line encircling the mantle. The gills and rhinophores are yellow or orange.
