Jd's are awesome fish! I have a pair in my 85 and theyre gorgeous, well until my male beat the heck out of my female then she got ick and tail rot but she's quarantined now. anyways, they're gorgeous fish! they have awesome personalities too atleast mine do. Theyre very brave for their size. my male (about 6.25 inches) bullies and shoves around my 7.5 inch red tail catfish. hes a little big for his britches. gt's are cool too. good luck with your tank!
