So I got a new betta, Casper. He's a cellophane halfmoon. He was doing okay last night, as good as a new betta can be. But today he's doing something weird. He's resting on a leaf of his silk plant but not moving at all. Nothing is moving. I mean, nothing. I see no movement in any of his fins, no movement in his gills, and when I tap gently on the tank nothing. He isn't dead because when I stick my finger in the water or try to scoop him up he swims away. What's wrong with him? I figured there would be some movement when I tapped on the tank...nothing. Any one know what to do? Thanks.
