We received a species of bred fish from Singapore which is usually only traded as wild collected ones: Mormyrus rume.
Currently the genus Mormyrus contains 24 species and subspecies. The determination is a very difficult task. Moreover, juveniles look totally different to adults. We obtained bred specimens of a species of Mormyrus from Singapore under the name of M. longiristris. A species M. longirostris does exist, but it originates from Mozambique and in that country work no ornamental fish collectors. It is much more likely the the fish belong to the species M. rume, which originates from Nigeria. We also get sometimes some wild collected M. rume from there.
However, both Mormyrus species are almost identical, not only externally, but also in respect of their aquarium maintance. The weakly electric fish are always involved in minor quarrels against conspecifics, what can be seen in harmless fin-damages. One should keep them solitary or in very large tanks in groups. Both species of Mormyrus can grow larger than 75 cm.
For our customers: the fish have code 151602 on our stocklist. Please note that we exclusively supply the wholesale trade.
