Hi Baylee, thanks! =) Yup, Dobby's jar is mostly the same. All the wisteria died, too easily, so I haven't replaced it, and I added bubbles (exterior air pump with a hose and air stone) - I only run it once or twice a day for maybe 15 minutes, Dobby likes to play in the bubbles for a while, swim in the bottom and let them carry him to the top. But when he gets tired, hanging out inside the pagoda or on the far side where he's protected from the current, I'll turn it off again.
I give Mr. Fish bubble play time, too. :) He likes to pop the bubbles, especially if they accumulate under his bridge.
I do want to get another Betta - I've even got a name picked out - but right now, I can't imagine any other fish swimming around in Dobby's jar. It would be too sad, because it wouldn't be Dobby, you know?
