RowdyBetta made floating tubes out of plastic mesh. Several of us liked the idea, and made tubes for our guys. My four fish all *love* their tubes. They're cheap and easy to make....
Get a sheet of plastic mesh. Cut it to size, being careful to trim off any sharp edges. Roll it into a tube and sew it closed with thread. (Total cost: about 59 cents.)
Here's Miami, about to swim into his green mesh tube. There's another white mesh tube outside of the tank (see bottom left of the photo), so you can see another angle.
Here's the original thread
