Fish show their colours with almost any food, but their colouring can be intensified by certain types of food, just like in humans with a diet of carrots. Mating or fighting males show how intense the colours can be in fish. JBL does not use cheap carotene, however, but natural astaxanthin (also a carotene) obtained from krill shrimp and spirulina algae. This is considerably more expensive, but it is a natural way to promote the beautiful colours of the fish.

JBL ProNovo Malawi Grano M 250ml
In the Rift Valley lakes of East Africa (Lakes Malawi and Tanganyika), many cichlids have adapted to graze the algae growth from the rocks for the microorganisms living in them (herbivorous growth eaters).

Some even eat only the scales of other fish (Plecodus). JBL JBL PRONOVO TANGANYIKA was developed for the predatory species. If both groups are kept together in ONE aquarium, it is essential you offer both types of food. Each feeding type will then receive the right food. Typical predators of Lake Tanganyika: Lamprologus, Neolamprologus, Julidochromis, Cyphotilapia, Telmatochromis, Calinochromis Typical predators of Lake Malawi: Trematocranus, Haplochromis, Nimbochromis, Sciaenochromis, Labidochromis.
