ROPE FISH (Erpetoichthys calabaricus) 8"

Not to be trusted with tankmates it can fit in its mouth but is relatively peaceful otherwise. It can even be maintained in small groups as it is not particularly territorial. Good tankmates include Synodontis species, larger characins and cichlids such as Severum, Angelfish, some Tilapia species etc. It shouldn’t be kept with very vigorous species, however, as it may be outcompeted at feednig time.
