I had another thread but it's really long and I don't think anyone is going to read it if I add to it. Sorry if I'm not supposed to start a new thread.

I have three frogs and two are fine. About a week ago one of the male frog's mouth got a white spot right in the middle. It didn't grow at all so I just thought it was probably a wound. Well, now he has two new white spots on his back. They're not fuzzy or anything. They almost look like blisters. I'm not going to lie, the tank is over stocked and even though the water has tested clean for months the last two tests have shown ammonia. I use prime which is supposed to irreversibly bond with ammonia, making it safe. I also use stress zyme. I do weekly water changes but until the ammonia is at 0 again like it was for months I'll increase my w/c's.

Any ideas on how to treat this or what it may be? If it's a fungus, which I always thought was fuzzy, I read good things about maracyn one and frogs. Otherwise I have no idea what it is. I'd hate to see my guy die. The only thing I can think of is ammonia blistering. Which coupled with the last couple of tests is very possible. I wouldn't think this would be a problem since I'm using prime but what do I know?

Should I dose with salt as you would with fish? I added some salt for a couple water changes when I first put in the Endler's and it didn't seem to affect them. It was a few weeks ago. I haven't added any since though.

Thanks for any help.

Any help would be greatly appreciated.
