he's also kind of tubby these days. i'm choosing to see it as a good thing considering how emaciated he was when I got him. The store I bought him from had had him for 2 weeks and he was kept in a bare bottom tank, which I'm pretty sure prevented him from sleeping at all the whole time he was there. The only way I can describe it would be that he was slightly insane when I bought him and he wouldn't eat. In my bare bottom QT tank all he would do was swim around in circles at a 45 degree angle with his 'nose' pressed against the bottom glass. I had an extra 40 pound bag of sand left over from when I set up my tank so I put rinsed some and made a 3 inch deep bed in one corner of the QT tank and he immediately buried himself in it and stayed buried for 48 hours. I could see the sand rising and falling slightly as his gills flapped. When he woke up two days later, it was like he was a normal fish again and started eating everything. I have a video of him burying himself in the sand as well, let me see if I can upload it to photo bucket. It's freaking cool.
