The fish is a mouth-breeder. This means that eggs are taken into the mouth by the female immediately after fertilization and hatched there.
The fish has a characteristic colouring and belongs to the rock cichlids.
It often behaves aggressively towards other fish species, with the exception of other African sea cichlids. With them a socialization is possible.


The lilac perch reaches a body height of up to 15 cm. Its basic colour is yellow with faint brownish stripes from dorsal fin to belly where they fade in colour, or purple to bluish with dark stripes.
The dorsal fin is flat. The caudal fin has one or more egg spots.

Gender differences

The males, also called milkmen, have a yellow body with faint brownish stripes. These run from the dorsal fin to the belly, where they become thinner and run out in colour.

The females, also called Rogner, are more colourful. They have a light blue to violet ground colour. Their stripes from dorsal fin to belly are dark to black. With 12 to 13 cm they are slightly smaller than the males.

In young fish the colouring is identical, only from a body height of about 4 cm the change of colour begins.

Water values

The following water values are required for optimal maintenance:

  • Water temperature 22° to 27° C
  • pH value between 7,5 and 8,5
  • Water hardness 3° to 15° dGH, whereby between 5° and 10° dGH is optimal

Feed and nutrition

The purple perch is a herbivore. It feeds mainly on plants and plant material. Occasionally it also eats animal food.
When feeding in the aquarium it can be fed with special Malawi food, but also normal dry food in the form of flakes or granules is possible. The Purple Perch also accepts food tablets. From time to time it can be given live food like Artemia or white mosquito larvae. However, these should be well dosed, as the Lilaprachtbarsch quickly becomes fatty

The ideal aquarium

The purple perch needs sufficient space for itself. The edge length of the aquarium should therefore be at least 120 cm. For this purpose the tank needs a capacity of at least 500 L.

The bottom should be equipped with well structured rock structures and slates. The males occupy these caves. They will become his permanent territory, which he will defend against everything else, except for females ready to spawn.

Due to its aggressive behaviour towards other fish, it is advisable not to keep the purple perch together with any other species. It is also often difficult to keep several milters. Therefore one milter should come on a small group of Rogner.

Keeping conditions

Not much is needed to keep purple perch tidy. Here is a short overview:

  • well structured aquarium in sufficient size
  • no other fish (except African sea cichlids)
  • warm, soft water
  • mainly vegetable feed
