i have one right now that's about 2" it should be fine in a 55 for life right. how do you tell the difference between male and female
cichlidfish;4635984; said:I think the 55g would be fine. If it is a cyano, then it could get 12'' and that is the absolute biggest. You most likely wouldn't be able to keep anything else in there since texas are very aggressive. The main way to tell sex is that females will have a blue-black blotch on the dorsal fin. If it is a cyano, then you won't even need a heater, because they like cooler temps. You will really enjoy having a texas.
