Since then I moved him to his own 7 gallon tank due to a goldie who decided he'd be tastey. At first he was his usual self but for the past few months he's had me worried. He was very inactive for a while. Lately he's been on the move a lot more, but doesn't seem to be eating anything. I've put a variety of green in the tank and none of them ever get so much as a nibble. I've also dropped shrimp pellets and goldie food in front of him hoping he'll eat it, but I can't tell if he does or not.
The weird thing is, when I clean the tank every week I get a ton of gunk off the bottom! Usually brown globs of dirt (or snail mucus? I don't know). If he's not eating I don't know how he's producing waste.
I don't know if he'd gone dormant for the winter or something, but the temp in the room he's in didn't change. Anyone have any suggestions or ideas?
