Floating logs are my favorite betta decoration because they look natural in a planted tank, and all my bettas like them. Sometimes they only hang out near them, but it's really cute when they sleep in the logs. The opening on top is really nice too. One of my male bettas puts a bubble nest in there occasionally, but it's really helpful for feeding. The surface agitation from sponge filters or flow from how filters can blow the pellets or frozen food away as soon as I put it in, and a few of my bettas will just not eat the food if it's not on the surface, or I can't tell if they're actually eating. I've trained my difficult bettas to eat in the floating log so I can tell if they're eating and how much
Bob-o loves it!
