My retic pup has been acting better and eating better than ever. Whats odd, to me at least, is that his color went from dark brown to very light brown. He's eating good, playing in the sand digging craters..swimming well, etc. All water parameters check out 100% good. He's on white sand in a well lit tank. Will they adapt their color somewhat to their surroundings, change as they age, or anything else? Something I should be looking for?
