Yes it's my blog. Pebbles loved doing that experiment too. Unfortunately the decorated vs. decorated wasn't even fun. She eagerly swam through the tunnel to check both tanks, and then refused the bare tank altogether and set up camp in the decorated. I'll have to do a post about that.
No, its a japanese name that means "Mist", which was my first thailand betta's name! :) My husband named her, but the name stuck with me so I still use it.
