My fan tail platy has a fuzzy like white thing on the end of it's fin. I tried to get a good pic. Sorry they are so huge, but any one know what this is? And what I need to do to fix it?

It's probably a fungus, but sometimes it is hard to distinguish between bacteria and fungus. Take the fish out and try to swab as much off with a wet q-tip, or you can snip it off with sharp scissors. It should come off, top dress it with a topical treatment. Save your money and use something like neosporin.
Try Melafix(anti-bacteria) and Pimafix(anti-fungal) together first it should do it.
Oh yea. Very nice fish!

Thank you! Will try the Q-tip and the combination of the Melafix and Pimafix.

Wow, I have to say that Melafix and the Pimafix works amazing. My friend works at a pet store, after work she stopped by with the stuff, I put it in, and literally an hour later that white fuzzy bulb thing was gone! Also the fish looked really bloated. And after putting the mixture in his stomach looked less puffier.

Thanks again!
