What a difference a day makes. The first few days all he did was lay in the corner of the tank and not move much. Even tried burying himself in the sand multiple times over the last few days. Then after eating this morning he started to move around and explore a bit more. Now since I got back home about 8pm tonight he has just been out swimming around like crazy which is really good to see.
On a side note I CAN'T WAIT to get started on the matching 3d background for this tank after the holidays, seeing it bare and looking like this just kills my OCD lol.
