I have a group of Male Betta’s, I have a Leaf Hammock in each tank. I see several of my Betta boys enjoying a rest on them occasionally, but Zen my E.E. Double tail especially loves his. Every morning I find him sleeping on the leaf and often during the day he is back on it taking a rest. He doesn’t have any problem swimming around the tank, but with his big flowing fins I believe he tires easier than the others. Resting there, makes it easier for him to take a breath when he needs to. If anyone has a E.E. Betta, a leaf Hammock would be a great addition.
