Polycentropsis

The African leaf fish, Polycentropsis abbreviata, is a predatory leaf fish from Nigeria, Benin, Cameroon and Gabon. Camouflaged to mimic a dead leaf, it stalks prey in a head-down stance and can swallow prey almost as big as itself. It is flighty and very sensitive to deteriorations in water quality, needs soft, acidic water and often accepts only live food. It is not recommended for the beginner.
