Well, i have 5 what i think are emerald green corys. Ive had them for about 2 years and to be honest i have never really paid much attention to them. They are in a big 260l tank and they live with a 3" green terror, 4" jack dempsy & a 6" tiger tilipia. I jus want to know why one looks so wide and blew out compared to the rest... Its been like this for at least 2 months. I think i read something about this, but i cant remember!
