They are all different. Your rt are kamfa flowerhorns though not rt and kamfa and vieja crosses take quite a long time to mature I would say 4-5" and they could be ready.
Lol its cool, I wasn't gonna stop looking till I found some rt. Those ate old pics one is starting to fade.would post new pics but they are so skittish. So is it the same with rt 4-5 inch before ready to breed?
Yea I would say 4.5 to 5" minimum before they are ready and thats if they are fertile. Best of luck and do update I hope the pearls spread on these guys.
