Could you let us know the size/volume of your tank and what the other inhabitants are/how many please? Any recent changes to your tank? New additions?

Also, what type of plec is it and how big?

I always find that larger common plecs can get agressive. I ended up taking them out and leaving only the BNs

do a 15-25% water change with dechlorinate etc.

check to see if hes still doing the same thing.

also check if hes targetting one fish or all of them.

is it big fish ? if it is, is it bigger then him? or is it smaller then him

Post in tropical discussion more members go over there and might identify what bugs they are.
Any red pierce marks on the fish.
