How well do they recover from serious physical injury? Specifically, pectoral and ventral fins bitten to 1 mm nubs barely protruding from their bodies. Chunks of fin and flesh bitten away from the tops of their bodies. Bruised snouts (open wounds I think) from rooting into gravel. Definite exposure to ich, although visible outbreaks currently.
Current nutritional intake is probably zero. They're being fed flake and blackworms, but the upper strata fish get to the food first.
