Confused betta owner here!
When I woke up this morning, I got a little concerned because I couldn't see my betta in his tank. After a moment a flash of something at the bottom caught my eye- he was almost burrowed, head first, under some of the ceramic "rocks" at the bottom of the tank (baby biorb) up against the center filter piece.
It looked like only his tail fins were poking out. I got worried that something had happened and unplugged the filter, and he swam right up to the top of the tank. I've never kept a betta in a tank with anything on the bottom of the tank to get into before, so I've never seen them pay much attention to the bottom. Any ideas what he was doing?
Should I be concerned that he could hurt his fins on the ceramic rock things that came with the biorb if he's poking around down there?
