thanks, I just took a good bit of wood out so that the gar has more room to swim. I have wanted to for awhile, but he was still getting spooked by me. Now that he is used to it and mellowed, i removed some and he seems much happier. i am going to be adding some floating water lettuce in teh next few days as well. I think that htey will like the dangling roots.I might remove some of the pennywort as its a bit messy.
