The floating logs have been great in my experience! It allows my boy to stay at the top and get air, and it protects him from the filter current. The hole in the middle is real great, he can get air there, and one time he made a bubble nest!
One thing to keep in mind though is that it does take up quite a bit of surface area. I have a 2.5 minibow and it covers about a third- maybe fourth- of the surface, and that's not including the filter. But the filter is a bit strong and he really likes it, so I'm keeping it. Might take it out for a week at a time if he looks like he is struggling.
Anyways, since I'm done rambling, I always buy my fish presents. Raccoon is the crazy one. ;3 kiddin'
