Ok my two cents. Aka meaning it's not worth much. But I have a rtc in a 75gallon. I feed him blood worms and pellets. I keep the water at 73F. I must say the temp must slow their growth. He grew maybe half a inch in a month. And my filtration turns my tank over 14 times a hr!!!! And my water quality is perfect. Take it for what you will or flame away. But on the same note I know I can't keep it in this tank for very long. I am prepared to spend serious money on this fish. Just saying about the growth rate.
