Hello, although I registered here a couple of weeks ago I never got around to posting. I've had fat tails for about three months now. I have two that are doing great. but the third I just picked up about a week and a half ago. he was the biggest at the store but still pretty young, Well he was eating great for a few days and hasn't eaten in about 4 days now. his tail looks really thin now. He is still kinda active. I've had him in with the other two cause he's not THAT much smaller and just picked up an extra tank tonight so that I can separate them. Is there anything else I can do for him? Is there anything I can do to help him eat? I'm really getting worried
