Description: Sturgeon Catfish have extended first rays on their dorsal, pectoral and caudal fins which forming long filaments, that give the fish extremely elegant look. These filaments may help the fish with orientation in the murky waters. Kite Pleco is relatively common in the aquarium hobby, but is not easy to keep and recommended only for experienced aquarists. This species often fades away after a few months of captivity and this is down to feeding habits. It requires fast, oxygenated water and will only eat algae and tiny microorganisms from flat surfaces, which is very hard to replicate in the aquarium. Success lies in weaning this fish onto prepared foods and this can be achieved by experimenting with water flow and tank decoration to create areas of strong current and quieter feeding areas. The other possibility to keep strips of slate and flat stones in a separate aquarium outdoors to cultivate algae on them, and place these stones into their tank after a few days.

There are only a few reports of their aquarium breeding. The breeding tank was 280 litres filtered at 4000l/h, where the current of the pump was directed to the back of the tank. The fish secretively spawned among the stones and wood. Spawning might be stimulated with some larger water changes. The female laid 45-50 eggs that ranged in size from 3.7 to 3.9mm. The eggs hatched after 8 days producing 12mm long fry.
