I was at a wedding last night and at each table there was a center peace of a vase with a lily and a Betta in it. I took it home last night and figured it can't be a good environment for the fish so I dug out a old goldfish bowl from 20 years ago and cleaned it out and filled half with tap water and let it sit over night, this morning I put the fish and half the water from the vase into its new home. He seems to be doing okay, he's swimming/moving around the bowl so I'm guessing thats a good sign that he keeps moving. The center peace came with a little bag of food and gave him a couple of flakes this morning and he ate them right away. Here's a picture of the little guy and wondering what else I can do to keep him happy without dropping a lot of cash?
P.S - I read the Betta fish FAQ/Guide so I think I'm on the right track.
