So I think I have finally come to a decision of what to add to my 135 as a final fish. I have a mature fem. chocolate, a 5-6 male green terror, and 5 or 6 more different small fish... sajica, loaches etc. Anyway, I was thinking of adding a Nic that a friend currently has ina 75 that needs a bigger home. He is about 8"-10", so probably fully mature. I'm not really worried about the chocolate, but I am aprehensive of the potential combo of the two males in question. Opinions?
