It started around 4 days ago, small red spots at his mouth corners. Day before yesterday it had almost healed but now it's ten times worse and he keeps lying down on the ground, a little tilted on his side with occasional activity. Other Shub has his top find down the whole time (so something is wrong, but I've no clue what). I'm using Esha 2000 in case it's fungus or rot or something like that + salt bath. Two days ago I had done 50% water change and ammonia cleanse. Didn't think he was gonna make it today.. Could use some advice!!
