anyone have some experience with thiese things? (I'm sure SOMEONE does) anyway, i have a smallish pair in my tank that seemd to have lost their vibrant coloring, and I cant quite figure out why, my water quality is on point, the only think I havent checked was H2O hardness, my phosphates are high, which I've known, its normal in my tap water... these lil guys have plenty of places to hide and are fed well, I just dont get it
