That looks like either a bruise or an early infection. If it's a bruise, some salt ( 1 tablespoon per 3 gallons of water) can help it heal. ( Make sure nothing else in the tank is sensitive to salt. ) If it continues to get worse with the salt, it will need to be treated with an antibiotic. Your water parameters will dictate which one(s) you should use.He seems fine in how hes acting but this has appeared overnight and has me concerned about his safety.
