Red, raw genatilia - I'm incredibly worried! HELP!

[mpmistr]

Yeah that looks like a bacterial infection but take that diagnosis with a grain of salt since I am not a vet. You may want to pick up Maracyn which can treat bacterial infections, just in case. I would not assume red leg (which is usually fatal, yes) yet because he appears to have an infected eye and cloaca.

Right now top priority is to stabilize the tank and stop it from getting worse. ACF truly do recover from most ailments by just having a proper environment. They are amazingly resilient animals.
