My arowana has something pertruding right in front of his pectoral fin. He has had this for about a week now. When I first noticed, it was a little red but the redness has gone away but it is still there. I was wondering if this is just an injury and it will just heal on its own or is it some sort of parasite and needs attention. The fish is very healthy and eats like a pig. Will try to get pictures up later. Thank you.
