Hey everyone, I'm in serious need of some help. I have a 3-4 year old African clawed frog and I woke up yesterday to see that she had a deep gash on the right side of her jaw just under her eye and what appears to be a blister in the same spot on the left side. There is nothing in the tank sharp enough to do that kind of damage and no other creature to harm her, either. All I can guess is that there was a blister on the right side as well and she scratched at it, resulting in the wound. Both sides are a deep red color. I was worried about Red leg at first, but, as far as I can tell, her legs are fine. The filter has been on the fritz and a layer of dark purple/ black algae had accumulated on the back wall of the tank, but only there, and the water in general was clear (there is some waste on the bottom of the tank, but not a copious amount). I've replaced the filter, cleaned out the algae, and am getting ready to do a water change. Is there any medicine or treatment I can give her? She won't sit still and is swimming into the walls, filter, and heater of the tank often, and the gash looks really bad. Any and all advice is greatly appreciated! Thanks!
