Some days he wasn't interested in food at all either, but he never went more than 2 or 3 days without eating something. More recently he's been better and will come when I open the hood. He's also been swimming around more lately.
His colouration is good when he's out and about, but very dark and pale when he's hiding. Which is normal. Its the frequency of hiding that is weird.
The worst part though is that every once in a while he'll go utterly spastic in his tank. Thrashing and dashing about very violently. He's suffered a few cosmetic scrapes, and I've added melafix and they seem to be healing, but everyday he has some new ones. I'm worried that he'll dash his head against the hood glass and stun himself or fly out the tank somehow. He also gets wedged behind the filter tubes sometimes and I have to wiggle the tube to free him. After the thrashing he will pace the tank as if on edge, and will eventually settle to the bottom breathing very heavily for a while. Then he's mostly back to normal.
I have no idea what set him off. It was very sudden that it started happening. He's never done anything like this before in the year plus that I've had him. I'm basically at a loss.
