This week we obtained from Nigeria a species of mormyrid which we haven´t seen for years: Brienomyrus brachyistius. This comparably small species (maximum length reported is 17.cm, usually the fish becomes 10-12 cm long) is a close relative to the species B. niger, which we were also able to import again (see http://www.aquariumglaser.de/en/fish-archive/miscellaneous-en/Brienomyrus_niger_en/).
The intelligent and playful fish are very lively. One looks after them not for their coloration, but for their funny looking behaviour.
We have specimens which are more elongate and larger, these we think are males, and deeper bodied, smaller specimens, which we think are females. Nothing is known about the reproduction biology of the species. The fish feed happily on any type of usual fish food (living, frozen, dried) that fits the mouth.
For our customers: the fish have code 103502 on our stocklist. Please note that we exclusively supply the wholesale trade.
