My first betta used to sleep under this bridge I would make for him out of rocks-I was a kid and was so amazed! So with my new betta Keller I made sure to build like 8,000 rock bridges for him. LOL he NEVER sleeps there. Keller sleeps at the top of a silk tree everynight. It's so cute he literally drapes himself over this tree. Lights go out, Keller perches. Sometimes he's actually upside down. It's quite adorable.
