I just inherited a 75 gallon tank. The guy who gave it to me had a 2oscars 3in, one 5in jack dempsy, one 5in green terror, one 6in jaguar, one 4in pike, and a male convcit 3in and a female convict 2in. He has this tank overstocked I know. I would like to keep the pair of convicts and one or two others. I was wondering what you guys thought on possible combos with what I have inherited. Thanks.
