Review on Optimized Single Leaf Betta Bed Hammock: Lightweight, Realistic, BPA-Free, Practical, Comfortable, and Safe Resting Spot for Betta Fish by Rachel Brennan

I have a large aquarium and wanted to make sure my rooster fish had plenty of space to rest, so I bought these. I already had a few from my previous aquarium. In total I placed 7 leaf hammocks on different levels. He doesn't really use them much. He prefers to sit in floating logs, but sometimes I see him pausing briefly on one of the leaves. They adhere very well to the aquarium wall and have a foldable foot so the foil can be tilted at any angle. There is nothing rough or sharp on the fins that could get caught.
