I added in the house from my 20 figuring that he might wqant to hide out in there, but he is swimming around like a champ now. He hangs out in the house while I am in the room doing things, but if I am just sitting around watching tv or something then he comes right on out. He is still eating blood worms. I guess that I should try to get him back to his old food now. I really dont want him to stop eating his food because of me feeding him these blood worms. AND! I was wondering, just about when do you think that I should move him and, mainly, the filter back to the 20? Since I moved the filter yesterday the water has looked super cloudy. I hate it! The parameters are still good though, which I guess is the main thing.
