Has anyone ever seen them breed, or start to breed, I have 2 that i have had for like 2 years and they are pretty sizable now, I'd say the larger is about
2 1/2" and the smaller about 2" i noticed the larger had a little kinda bump under it ad the smaller was kind of sticking it's head into it (weird fish) lol. Common sense would tell you that maybe this is some part of breeding, but I have never bred Cardinals so I have no clue???? Anyone have an idea?
