Butterflyfish is so weak and limp

[bensoo00]

My butterflyfish was like floating around and just basically limp through the tank at night. He became really timid and slow after I introduced a long nose hawk fish but I’ve never seen them fight. I do assume he has been injured but I don’t know what to do. He is breathing and sometimes swims but he is just letting the flow carry him around.

I suggest quartining all fish before you add them. When it is not qt it can be used as a hospital tank. This guy would go in it for observation.

To avoid any more stress I would say put him in a large acclimation box inside your tank, or do a 5g tank with water from your tank. Be sure to put in a hide (PVC pipe) Let him try to get oriented again.

Unfortunately this fish is moribund and likely not able to eat or swim from this point forward
Quarantining will make things worse
I can’t suggest any method or medication to change stathis of health
Some causes are:
Injury
Starvation
Internal issues
Aggression
Water quality
