It was right after he ate, he's usually not that round lol, he's maybe 4 inches now he's grown a bit :], I feed once a day, usually a small bit of what I'm feeding that day, and a snail or 2, or one if it's a bigger kind. How much should I be feeding? I feed until he looks about like in the picture, should I feed less? Also, his foods are defrosted in tank water, there are fish vitamins?
