My brown bullhead catfish hasent been eating for awile. I recently brought it in for the winter and i thought that was why but then i remembered that he wouldnt eat in my pond for a little wile either. The water hasent changed. He used to eat pellets, worms, feeders, leftover food, basically anything i put in. Now he wont even go near the food i put in. any problem? maybe its just his metabolism is lowering for the winter.
