I changed my betta's tank around a bit when I did the water change last night.
I moved his existing decor around and added a couple of new plants as well as a "proper" in-tank thermometer.
He's been busily exploring since I put him back in the tank, which was the whole reason for the change, but his new favorite accessory seems to be the thermometer.
I really think he'd be thrilled with a tankful of nothing but thermometers, he's hanging out with it like it's going to feed him.
I also bought him a small container of Freeze-Dried Bloodworms to use as treats.
He won't eat them at all, he sucks 'em in and spits 'em right back out.
I guess that if he's never had anything but processed fish food the real stuff must seem a little strange.
