Hi everyone,I have a breeding pair of Red Isletas aka Redhead Barred Midas. Have had them since birth, bought several and let them pair up. They are a little over a year old. Have had 2 successful spawns. Hard to find info on them. Main thing is that I don't know how big they get. I had them in a 30long tank (36 inches) in my bedroom. They did well, had 2 sets of fry, are very personable fish. I moved them into a 40gallon, then a 55g, thinking they needed more room. I swear, they ARE NOT happy!!! They hide, never come out, etc.....it is breaking my heart. Everything I read says they are very aggressive, but that has not been what I've seen so far. They seem shy and not aggressive. Matter of fact, the first set of fry stayed in tank with them. They bred the second time, I was in process of moving first fry so they didn't eat them. Well, the dang first set of babies ate the second set!!!! No kidding..........so how's that for aggressive???? hahaAny insight on personality, etc would be helpful. I just know they aren't happy right now, but trying to give them enough tank space. Dad is about 8", Mom is about 6" and they are over a year old. I am not sure how big they will get. Maybe they are smaller??? I will search the site for info, but hoping to get some feedback from experienced keepers. I moved them out of bedroom because when breeding their eyes turn solid blood red. It was a bit freaky and unsettling at bedtime...but they are truly interesting fish! Thanks!
