Har ingen egen erfarenhet men här är urklipp från seriouslyfish.com som är en tillförlitlig sida:
Very peaceful for a cichlid, but is territorial when spawning. Don't be tempted to keep it with very vigorous species as thomasi is a shy and retiring little fish. Good tankmates include small characins, other African dwarf cichlids, Corydoras and smaller anabantoids. Males are aggressive towards one another and sufficient space must be provided if more than one pair is to be kept. Allow around a square foot of floor space per male.
Often overlooked when seen for sale, as juveniles can appear a little dull, Anomalochromis thomasi is actually one of the best choices for the newcomer to dwarf cichlids. It is relatively undemanding, peaceful, easily bred and quite beautiful once settled into the aquarium.
