Ok so I got my ADF a couple of months ago. He seemed fine but wasn't very active. A couple of days ago I believe that I had an ammonia spike in my tank. I think that this is where it all began. During this spike I lost the guppy that I had. My betta seemed fine after I did a 50% water change. I noticed that my ADF was on his back so I got scared that he might have died but then he tried swimming to the surface but only made it a couple inches before he began to float back down onto his back. I picked him up and brought him to the surface so that he breathe and put him back into the tank. The same thing happened. This time I saw that he wasn't using his legs to swim. I put into a small plastic container filled with 3 inches of waters and let it float in the tank. Since then he has regained some control over his legs but still can't reach the top of the fish tank. Any ideas on how to treat his condition or what it might be? I have a 10g long tank with a betta and java moss that I keep at around 80 degrees Fahrenheit.
