Last week we presented to you our freshly imported Golden Congo Tetras (Phenacogrammus aurantiacus). The slight fin damages of the fish are as good as cured completely now. Many of our customers now ask for “safely” sexed specimens. All we can say to that is: of course large, dominant males are easy to recognize. But all other fish must wear a big question mark. In all Congo tetras exists a clear sexual dimorphism in respect of the anal fin structure, dominant males have moreover a long extended dorsal fin in P. aurantiacus. Males also become bigger than females. But non-dominant males and large, dominant females can be hardly told apart from each other. And also “absolutly safe” females can proof later as young, unripe males. It is simply impossible for us (without killing and dissecting) to be 100% sure about the females.
For our customers: the fish have code 158254 on our stocklist. Please note that we exclusively supply the wholesale trade.
