🐟 Physical Description

Dorsal spines (total): 13; Dorsal soft rays (total): 10 - 12; Anal spines: 2; Anal soft rays: 11 - 12. : fusiform / normal; Cross section: compressed.

🌀 Behaviour

C. parasema prefers peaceful tank mates and abundant hiding spots, as they are frequently preyed upon in nature. It is a favorite species among aquarists because it is active, but less aggressive than most damselfish. However, these fish will sometimes harass more passive fish in an aquarium. In addition, despite its comparatively peaceful nature, this species can be territorial with members of its own species. They tend to become more aggressive when kept singly. This aggression can sometimes be reduced by keeping them in small groups of odd numbered fish (three to seven). They do show schooling behavior when kept in large groups. Despite its hardy nature, C. parasema also must not be placed in an aquarium with larger predatory fish such as lionfish, and grouper which will often see it as a food source.

🦐 Diet

In captivity, C. parasema shows a preference for spirulina, flake foods, and mysis shrimps. However, they tend to go after most fish foods, whether frozen, freeze dried, or live. These fish tend to feed towards the bottom of the tank.
