looks bad my friend.. do you have any ornaments in the tank? it looks like he scratched himself.. treat it with antibacterial solution.. i use ocean free general aquatic aid.. there are other products though..

bump temp to 80 to 85 and salt and add more air stones.

heater burn? agree with salt and upped temp.

yup up the temp and add salt. I've seen worse and they all pulled thru just keep the water clean.
