Shelled peas, blanched courgette, spinach and chopped fruit all make good additions to the menu. Once settled into the aquarium the fish sometimes ascend into midwater to feed and in a rivertank-style set-up as described above will often be seen browsing the biofilm that tends to form on the rockwork.
