Here is a previous post I put up today: http://www.bettafish.com/showthread.php?t=55780
but now there seems to be a new issue.
Yesterday he was resting at both the middle/bottom of the tank and the top of the tank and he was resting at the bottom of the tank this morning as well. I just came home and went over to check on him, and he actually swimmed around a bit...but I watched him a few times as he swam down to the bottom of the tank with all his might, only to float straight back up again against his will. He did this a few times until he seemed to give up and just floated at the top. I know I've read about this before, but I can't remember what it is. Any help?
