I've forgotten how weird they can be! LOL. Spent awhile figuring out the tank set up and getting his water right. I also had to train him on how to eat pellets at the surface as opposed to on the bottom of his cup. That took awhile and was scary because he wasn't eating and it was making me concerned.
I also thought he might be hiding in the corner of his tank because he keeps seeing himself in the reflection of his tank. So I put one of Noah's drawings on the back. He flared at that and everything else since then. He goes in his cave which took him about 5 days to find! LOL.
