African dwarf frog help.

[brittany_b415]

I know it's a post for unhealthy fish but I have a 46 gallon community tank with guppies, platys, cories and two African dwarf frogs. Today I noticed one of my frogs has what appears to be a blister on him. I'm not sure if it's from him hanging out behind the heater, or his skin trying to shed. I only noticed it today so I'm a little worried. It doesn't look fuzzy like a fungus. Plus I just finished a treatment in my tank for bacterial and fungal problems (one of my guppies had a swim bladder issue). My water parameters are fine, 0 ammonia, 0 nitrite, 20 nitrate and my temp is 25 Celsius. Any ideas what this is ??
