Several color variants are sold commercially under the name of Mastacembelus
or spiny eel. The long snout acts as an organ of touch: only the head remains sticking
out when the fish buries itself in the sand for protection. It is best to keep only
one specimen, otherwise there will be constant fighting. Be careful too that this
species does not escape from the tank, as it is very agile. Breeding in captivity
is impossible without hormone injections. Size: 20 cm.
