Also one tip -at any time when you have a sick fish be careful and do not cross -contaminate anything between all of your fishy and sick one.
Oh and good luck! Thank you for an update, its always makes me happy to hear a good news:)
lol i had to read your original post to remember what was the problem. Well i would think if he is still in this world he should be fine! The post was made in 08/13. I hope you can put him back in his own tank. I really think that bettas live longer in their own tanks ,and get stressed in the bigger community tanks.
Finally getting some progress. I partnered him up in the double tank with one of the other boys to try and build his immunity.
Problem is he cant play nice and keeps ramming the barricade, hopefully not much longer and he can go back to his forever alone tank.
(sorry it took so long, for some reason I got no notification about your post to my email)
