wound or parasite??

So I came back from vacation to find one of my male guppies hiding in the thickest planted spot in my tank he only came out for food. I then noticed last night that he had a white bump near his pectoral fin on one side. I moved him to a hospital tank with some salt. This morning he is lathargic and hanging at the bottom except when I put food in. I am including a picture but it just looks like a white bump. When I first got this guppy he had some kind of skin/gill flukes which I treated with Prazi Pro. He has been healthy since then. Does anyone have an idea what this thing is? Should I try to pick it off with tweezers? Or just keep him with the salt and keep my fingers crossed?

Our Male Guppy

Hello dsk...

Salt is good for "Livebearers". No more than a teaspoon for every 5 gallons of replacment water is all that's needed. Most pathogens don't tolerate even a trace of salt in the tank water. More than a teaspoon and your aquatic plants won't do well.

I don't quarantine my fish and don't think it's needed, too stressful. So, dosing chemicals isn't an option. They can affect your other fish, plants and sometimes kill your beneficial bacteria.

I suggest an aggressive water change routine for the next few weeks. Change half the water every week, no slacking. Make the new water a bit warmer than the water that's in the tank and dose one teaspoon of salt for every 5 gallons of new water. Get some Anacharis (Waterweed) and float it in the tank. I find this fast growing, leafy plant helps calm my Guppies. Good nutrition is important. I feed mostly frozen, because there are no additives. Feed frozen brine and mysis shrimp, plankton, beefheart and krill. Just a little every couple of days. I also feed a bit of minced garlic. It's a natural antibiotic, with a high vitamin content.

The combination of a lot of pure, treated water flushed through the tank, a little heat, salt and good food will generally help.

Just one reporter's opinion, though.
