Yesterday i went to the only place that i have been able to find Gymnogeophagus Balzanii, i have been searching for over a year now, they had 4 at about 5cm, i was looking at them and i thought i could tell atleast 1 male but was not 100% sure on the others. Considering they were $150 each i was hesitant to buy all 4.
I went and looked around the rest of the shop while i thought about my purchase, then when i went back there was a female laying eggs, i dont think the male was interested in her but at least i could pick a definite pair.
So now i have a pair of the awesome Gyms.
