I may need to rethink my pellet training program to include some cage rearing once water temps warm up in June. I do think these RES will be fine now that they are in the pond and have access to a more varied diet. I did give them small amounts of bloodworms and nightcrawler pieces to vary their diet but apparently this didn't help with what they need for coloration in their diet. Based on Jim's comments in the other thread I believe carotenoids are most needed for sexual maturity and successful reproduction.
