I saw some fish labled as green terrors at petsmart, but they didnt look like GTs to me , they looked more like some type of acara. So i picked one up (he or she is only 2") because ive never been able to find any sort of acara besides false GTs which are much too aggressive for my tank. I need help finding out what he really is but i dont know how to upload photos or anything! I need help because i know once he grows big, pretty and aggressive petsmart wont take him back . Help!!
