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
Doesn’t work for internal. More for external. To me it looked outside but can’t make it out in the pics.Okay just didn't know if paragard would work for internal stuff
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.It's literally a bubble underneath his skin
