Review on 🐠 Floating Fish Feeder Ring for Round Aquarium Fish Tank - 7.5cm Feed Circle by Chris Murphy

That's cool! We have two males and the filter sends their food to many places. One Betta immediately realized that his food would be herded into the ring. He also quickly built a bubble nest in it - see photo. The other one is sleeping underneath it now I think because it keeps him a little submerged compared to napping on the surface of the water (he likes to swim sideways - for the first month I kept checking to see if he had died but it turned out that he was just lazy) ).
