RE: using cc/sand for cichlid tank?
Erin,
River City is a good local source (and a sponsor, too). I agree electric blues with the electric yellows is a good choice. I have both in the same tank with Flauvescent Peacocks, shell dwellers, Black Calvus, bristlenose catfish, giraffe cats, and a huge pleco. I feed Spectrum and Spirulina. LMK if you have any questions.
