the bubbles all over are off-gassing. was that water straight out of the tap? that will always happen when you take water right out of the tap, put it in a tank, and the bubbles will appear in a few hours. i like to keep a gallon or 2 of water in a jug with no top on it for water changes. that will eliminate the issue with bubbles in the future.
he's really pretty!! oreo's a cute name, though. i like it. but if you really hate it, what about something regal like "Patrick" or "Daniel."
