Lol! I have 2 in my 75g. 1 of them pops out everytime I think I lost him. I don't even bother looking for him anymore. When I had some in with one of my Betta's awhile back they did really good. But a few of them had ich. Then the whole tank got it, including my Betta. So after clearing the ich up I just decided to let my Betta have the tank to himself. Now it has a divider with another Betta on the other side. If I was to make my 10g Betta tank a community tank again I'd go with Otto's cats, and endler guppies again. And, would diffently have it planted.
