Leptobarbus rubripinna



Leptobarbus rubripinna, also known as sultan fish, naturally inhabit the Mekong River basin in Southeast Asia (Laos, Thailand, Cambodia, Vietnam). Adult fish stay in deeper waters, while juveniles prefer to swim in the shallows. During the rainy season, fish migrate to temporarily flooded floodplains and forests where they spawn. In general, the fish are not demanding, but are quite large, which imposes certain requirements on the size of the aquarium.

The body of Leptobarbus rubripinna is elongated, cigar-shaped and silvery in colour. The head is small. There are reddish spots on the pectoral, pelvic, caudal and anal fins. Dorsal plumage is translucent and fairly high. Sexual differences are poorly expressed, mature females have a more rounded abdomen than males. The maximum size of fish in nature reaches 1 m, while in aquarium conditions, their size is much smaller.

Considering the considerable size of the fish, they can be kept in aquariums with a capacity of at least 500 litres. The interior arrangement of the aquarium does not impose special requirements. It is the water quality and sufficiently large space for the fish to swim freely that are more important. However, if you want to recreate in an aquarium conditions as close to natural as possible, you can design the internal design so that it resembles a flowing river with a substrate of stones and gravel of various sizes.

Leptobarbus rubripinna, as well as many other fish species, do not tolerate the accumulation of organic matter, so you need to take care about strong filtration and do not allow the accumulation of waste products and food residues at the bottom. Sufficiently strong water flow, e.g. by using a water pump, and increased aeration should be provided. The aquarium must have a cover, as Leptobarbus rubripinna rather timid and during a scare may jump out of the water.

Water parameters: temperature 20-26° C, hardness dH 1-15°, pH 6,0-8,0. Requires a weekly replacement of 1/3 of the aquarium water with fresh.

The menu of fish in nature are a variety of food plant origin, zooplankton, crustaceans, aquatic and terrestrial insects. Under aquarium conditions the fish will eat practically any food they are given. To enhance their colour, feed them regularly with live and frozen food such as bloodworms, daphnia and artemia. You can also give courgette and fruit slices, spinach or lettuce, earthworms, shrimps and mussel meat. The fish should be fed 1 to 2 times per day.

Reproduction

Leptobarbus rubripinna does not breed in aquariums. Spawning can only be achieved in fish farms in Thailand by hormonal injections.
