OK my 2 jewels are very strange with their colors. In the LFS I picked the one because its colors were awesome. I have never seen it come back since I brang it home. The colors do come and go one minute there is some color around the mouth and the next minute its gone? What makes there color come out? I know probably diet but mine eat Tropical Flakes, Spirulina Flakes, Floating Cichlid pellets, shrimp pellets, frozen bloodworms and soemtimes beefheart. I think that is pretty good. Am I missing something I should feed?
