A few weeks ago I saw a pretty, soft blue delta tail, VERY small, half the size of my boys, with black tipped fins. He had finrot and split fins, not bad, but enough to make him look pretty beaten up. I didn't have the money the last time I saw him to get him AND a decent bowl to put him in. Well, I went to get some hamster supplies today, and that same betta was in an inch of greenish water. It looked like his fins were doing better, though. I took him, and got a one gallon bowl for him. I don't like the bowl much, but it was all I could afford. I may upgrade him when I get the money to do so.
