Well since I am gonna keep my 6 inch Male Green Terror in a Large tank....Ive Been really wanting to buy a Red Devil....So tomorrow I am gonna buy a baby 3inch Red Devil to go with my 6inch Male Green Terror...I will grow the Red Devil out in a 60g with the 6inch GT....I dont really know about Red Devils but I am just wondering What size tank would I be eventually looking at for these two Fish? and also would they make good tankmates?
