Fighty found his cave yesterday, after a week in his new tank. He had no problems getting in or out, and he loves sitting in it now. If I can catch him in there with my camera sometime, I'll post a pic :) He has also been sitting on the plants in his tank too, just chillin'. I think he really likes his new home.
He also got to try some bloodworms the other day. The first time he had them, he spit them back out. But, I tried again yesterday, and he ate four (they are the freeze-dried ones). I think he likes them now :)
