When do they develop that amazing blue sheen? Mine are only two weeks in my care and they have improved vastly from how they looked in the LFS, but they look nothing like yours! Can the colors improve over time and with age? I do feed a variety of foods; frozen shrimp, bloodworms, tetra colorbites, flake, shrimp pellets, crab bites and sinking wafers on a varied schedule. They are not aggressive eaters, so they haven’t really figured out the frozen foods yet, but anything sinking they will pick at.
