Update:
He seems to be starting to do better. The white spot ended up going away before the ethylene blue got here. I let him sit for about a half hour in the methyl blue dip at half the dosage since the spot went away. I needed to take him out of the tank to clean the tank anyway. I needed to remove a bunch of rocks I had put in there that made it nearly impossible to vacuum good. The stress coat seems to be helping a lot too, he seems to be doing better since I added it. He's still scratching but much less than he was. He also is eating more aggressively again, not as aggressive as before though. He seems to be improving every day now. Thanks for everyone's help so far, Ill post more updates if anything changes.
