My betta has lived in a 40 gallon tank with several other fish, mainly mollys and tetras for about 5 months, he has had 2 bouts of white spot, and has had his entire fin eaten off (by a fish who is now gone) but has always grown back strong.
My tank is healthy and no new fish have been added for 3 months
I found him floating on a plant, then floated to the top vertical, immedietly i have seperated him and this is what hes doing now...
He has a wierd kink in his body right between the bottom and back fin, and he keeps having little fits and twitching really bad with it!
PLEASE HELP ME AND MY FAVORITE LITTLE FELLA :(
If you have any ideas what might be wrong, and what i can do, please post.
