I've had my ADFs for a year now, and they have done really well, so far - two in a 10 gallon tank. They were VERY fat and sang and attempted mating. Lately they're lethargic and aren't eating. Both are getting very thin - one is almost always hiding. At least one of them is shedding. Nothing has changed in food or environment. Is it wintertime? Do they go through a slowdown? Any suggestions or advice would be appreciated.

Any suggestions for helping the other? Besides getting the ammonia back down, anyway... Thanks!
