SEA 08

Chromis may also suffer harassment from other Chromis in the aquarium. In schools, Chromis often adopt a pecking order where the smallest of the group may become tormented to death. Thus the schooling issue is the subject of much debate and concern. It is often recommended that groups of Chromis be kept in schools of no less than 6, as the pecking behavior is more broadly dispensed among the smaller members. However, aquarists have found that pairs and sometimes trios can be grouped successfully without pecking order issues.
