Haha, well I'm sure he enjoyed the extre space! How large is that tank? I think my little pac was cold this morning, so I put a 10 watt cfl bulb on his tank to warm him up (the 6500's throw heat pretty good ) until I pick up a 10 watt heat pad this weekend. (Put it on the SIDE of the tank, right?) I want my lil pac to be warm, it was about 69-72 in his tank this morning, but it's now up to around 78, I want to keep him at around 80-82, becuase he's so small (3/4" STVL).
