I have had some success with Angels together back in the day but not any experience with Pygmy's together. Have a reef with a small C.Argi and friend wants me to take his pride and joy Coral Beauty as he is taking down tank. CB would be the larger fish by a decent margin. My C.Argi is small but feisty if bothered. Gave away my SPS and most other corals so picking not a worry and my C.Argi never did anyway. Just wondering what those that have had together think. Thanks for replies.
