Blood underneath his gills

[Denise T]

Not sure if he hurt himself or if something else is wrong.  He was trying to get under a small section of driftwood so i removed the drift wood.  Does anyone knows what this is?  Or what I need to do?  I dont know if i should panic if this could be hemorrhagic septicemia?  Do not know how he would have gotten that.  Please advise if you know, and how to treat.

Thank you

No real experience with this kinda thing, but never a good time to panic.  
 

Is he alone in the tank, or at least big enough the others won’t pick on him?  Moving him to a hospital tank a touch of salt my help the recuperation process if he shares the tank.

The water temps are good.  My pH is 7.4, 0 ammonia, 0 nitrites and 10 Nitrates.  He is acting fine.  Hes my beautiful boy.  He is a pretty large severum, but not full grown yet

Could be an injury could be bacterial I think it would be worthwhile quarantining him and doing course of kanaplex and aquarium salt 1 table spoon for 3 gallons the salt will add essential electrolytes and aid Gill function @Denise T
