I have had the gold flake angel for about two months. I feed spectrum pellets and spirulina About 1 and 1/2 inches and growing. The potters angel, I have had longer and it is pretty decent size 2 inch plus. Both really healthy and active. I got the gold flake from bullitr. Gold flake is nipping at sps but leaving LPS alone. Don't think potters is messing with anything. Decided I like my sps more than angels and want to take out any potential threat Color is awesome on both. Pictures to come later this afternoon
