Description: See pictures.
Care: Really easy to keep fish that does well in virtually every type of tank. Not particular to waterconditions or environment, some hideouts and some floating plants are appreciated, as well as a some current. The fish breathe atmospheric air, hence the tank should be covered to reduce the difference in air and watertemperature. Besides that, the fish sometimes jump out of the water when going up for air, so some space between the cover and the water is recommended. Sharp gravel should not be used to protect the barbs Brochis splendens when they dig for food. Brochis splendens should always be kept in groups of minimum 4 animals, but it's better to keep a large school of 7-8 fish in in large tank.
Temperature: 22-28 degrees
Feeding: Omnivorous, all food is taken. Make sure they get food, since they cannot live on detritus alone!
Size: Up to 7 cm(9 cm has been reported by Hierronimus)
pH: 6.0-8.0
Breeding: Difficult. A lowered waterlevel and frequent waterchanges with soft acidic water, which should be a few degrees colder, will often induce spawning. Tempered light, a strong current, and peat filtration are recommended. Feed the fish well, and provide them with a substrate like green cotton. Up to 300 eggs can be laid by a single female, which are mostly deposited in the upper regions of the tank on the glass and on floating plants. The eggs are a bit larger than corydoras eggs. The fry and juveniles are completely different from the parents, brownisch, with spots, with an extremelely large reddish brown dorsal fin.
Sexual dimorphism:Males are thinner than the females.
Prices:Netherlands: 3-5€
