Synonyms:Micralestes interruptus, Boulenger, 1899, Phenacogrammus interruptus, Eigenmann, 1907, Hemigrammalestes interruptus, Pellegrin, 1926, Alestopetersius interruptus, Hoedeman, 1951, Petersius codalus.
First European import:Germany, 1950, by Aquarium Hamburg.
Care: Larger tanks with lots of free swimming space are necessary to keep 3 or more fish. Water conditions soft, neutral to slightly acidic water, regular waterchanges. The tank should have some planted regions, and preferably be placed in a sunny location. The coinhabitants of Phenacogrammus interruptus shouldn't be aggressiv, since the fish will become shy in such a setup. A dark soil and some floating plants will better display the colors of the fish
Feeding:Omnivorous all food is accepted. Insects are highly appreciated!.
Size:Males up to 8 cm, females a bit smaller, 6 cm.
pH: 6.0-7.0 Hardness KH preferably low!
Breeding: Soft acidic water, KH below 5, temperature 25 degrees or more. Mating occurs both with pairs or in schoals. The fish usually mate in sunlight near the bottom of the tank. The up to 500 eggs mostly sink to the bottom of the tank, and hatch in 5-7 days. After breeding it's best to remove the parents, although they hardly touch the eggs. The fry should be fed infusoria in the beginning, since they are extremely small, and grow quite slow, artemia nauplii can be fed after approximately two weeks.
Sexual dimorphism: Males have elongated dorsal, anal, and caudal fin.
