Was browsing amazon and came across something called a "Betta Hammock", apparently its a plastic leaf with a suction cup that you attaches near the top of the tank and the bettas like to lay on it? Anyone on here ever buy that?
I've used them before. They work nicely, and the bettas do seem to like them. However, one major problem with them is that the part of the leaf that attaches to the suction cup is of very thin plastic encasing a metal piece and tends to rust fairly quickly. If you get one, just be aware of that and watch for any signs of such. Or, do as the above member did and make your own.
