Have a payara that just developed a bubble or lump under his one pectoral fin any help would be gret to know what this could be and how to treat
 
Looking to find out what it is and what I should treat it with if it's a parasite or bacterial infection

Really can’t tell what it is from the pics. Would watch it. Can try a round of paragaurd if really worries about it.
 
It's literally a bubble underneath his skin
Sorry for the late reply. If it’s still there I’d try watch it and see if it’s grown a bit. If not I’d try a round of triple sulfa and metro.
