🌀 Behaviour

Behavioural data for African snakehead is currently being reviewed.

🦐 Diet

P.africana is an ambush predator that feeds on smaller fishes and invertebrates in nature but in most cases adapts well to dead alternatives in Captivity. Some specimen accepts dried food though these should never form the stable diet. Young fish can be fed with chironomid larvae (blood worm), small earthworms, chopped prawns and suchlike while adults will accept strips of fish flesh, whole prawns, mussels, live river shrimps, larger earthworms etc. Older individuals do not require feeding on daily basis, with 2–3 times per week sufficient. Note that, this species should not be fed mammalian or avian mean for example beef heart or chicken since some of the lipids contained in these cannot be properly metabolised by the fish and may cause excess fat deposits and even organ degeneration.

🥚 Reproduction

The eggs of this species float to the with floating plants covered surface where they are guarded by the male.
