Okay, so I was taking some pictures of Froakie in the quarantine tank to see if the camera could pick up anything my eyes couldn't see.. lo and behold! The flash picked up some very small lighter green spots on his back, (will post when I can) that look very similar to the spots other frogs on this forum have developed when they have a bacterial infection. Although I may be too late in finding this, I've applied some Neosporin without painkiller to his back in the hopes that the antibiotic properties might help him. If I could do more, I would, but its 10pm at night so I wont be able to do anything else till tomorrow. Still keeping him in quarantine and changing towels and water everyday to try and minimize the bacterial load (if that is what it is) in his system
