I have 3 rt babies in with a couple breeding pairs of cons. So maybe it is aggression over territory. They have all been together for a few months and I'm just now seeing the color change. Can they pair off and breed at 2"?
i think the carpintis i had started pairing off at about 2.5in but they didnt start breeding yet, some cichlids can pair off quite young just not actually breed till they get a little larger, 2" does seem a bit small but its not impossible that they may have formed a pair already
some red texas actually dont show much or any red, its the super red texas you are thinking of so it very well could be a red texas and also they take time to fade with age just like a FH would, even the super reds start out looking like a regular carpinte
