Today I moved 4 neon tetras and some guppies and zebras to a larger tank. All fish seem to be acclimating well except for one small neon. His colors have noticeably faded and he is not as active as the others. Are these just temporary stress symptoms due to the new tank, or are they symptoms of disease? I don't want to remove him from the tank, but I don't want to put the other fish ar risk in case it happens to be a disease. I would appreciate some advice. Thanks! Scott
