Trematocranus placodon



Trematocranus placodon, Cyrtocara placodon is endemic of Lake Malawi. The fish stay in shallow water, among the thickets of aquatic plants. In nature, they feed on mollusks. The fish have well-developed pharyngeal teeth, with which they easily crush and pulverize snail shells. These are ideal fish for a large Malawian community, but they are very rare to find on sale.

Trematocranus placodon has an unassuming coloration. The body of the fish is slightly golden in color with three black spots - one in the central part of the body and two others at the base of the caudal fin. The mouth is small. Adult males are more brightly colored than females and slightly larger than them. The maximum size is 25 cm.

The fish are territorial. Each male requires a large enough territory, which he fiercely guards. In this regard, should not contain multiple males in a small tank, otherwise there will be constant conflict between them. At one male should have 2-3 females. Keep fish is recommended in a species aquarium of 250 liters. In large aquariums, together with Trematocranus placodon, can contain, for example, Cyrtocara moorii.

At the bottom of the aquarium should be placed a lot of stones, making them caves in which fish can swim freely. As the substrate used coarse-grained river sand. The perimeter of the aquarium is desirable to plant tall plants such as vallisneria. Also need to take care of a free place for swimming.

Water parameters: temperature 24-28° C, hardness dH 10-25°, pH pH 7,6-8,8. Requires filtration, aeration and weekly replacement of 1/3 of the aquarium water with fresh. The water current in the aquarium should be minimal. With poor water quality fish on the body sometimes form small abscesses, which are treated with methylene blue in the proportion of 0.1 mg/l with a small addition of table salt, for about 10 days.

Under aquarium conditions, Trematocranus placodon will eat almost any live, frozen and dry food. If possible, it is desirable to include snails in their diet. Food is given 1-2 times a day.

Reproduction

Breeding Trematocranus placodon in aquarium conditions is quite difficult. It requires a spawning tank length of about 1.5 m, with the environment as in the main aquarium. Need to take care of the presence at the bottom of a sufficiently large area of sandy substrate free of stones. Spawning aquarium perimeter are densely planted wallisneria and planted in its 1 male and 3-6 females.

The male digs a hole in the substrate and starts attracting females to it, showing them his bright coloration. When one of the females responds to the male's advances, she swims up to the spawning site and spawns there. The male then fertilizes the eggs, and the female immediately collects all the eggs in her mouth. In total, the female hatches up to a hundred eggs during the spawning season.

The female incubates the eggs in her mouth for about three weeks. During this time she does not eat anything at all and should not be disturbed, because when frightened she may swallow all the eggs or just spit them out. The mouth of the female leaves the fully developed fry, which should immediately desirable to transfer to another aquarium in order to save their stock.

The fry are quite large and feed on artemia from the first days of life.

Trematocranus placodon has a lifespan of about 8 years.
