Is my betta moping? Do they mope? He was so curious and interested in stuff before. Now he spends a lot of his time either near the duckweed, sadly looking up at it it seems, or else in a little cave he made for himself between two other plants and some larger rocks. Now and then he swims around, and if just the tank lights are on he'll menace his reflection for a bit, but he's just sort of moping for the most part. He does respond to being fed.
