How to get rid of parasites? PLEASE HELP

[uelissa]

So I'm pretty sure that my guppies have parasites. Last night, I noticed something red on one of my females but didn't think much of it. Before I went to bed, there was a large red spot, so I put her in a floating breeder and hoped for the best.

When I woke up, her whole side was red, and something was coming out of it (pictures below.)

A few days ago, one of my male guppies was really really fat, and died right in the morning. I was just thinking that he was bloated.
Now I'm looking at my guppy tank, and I notice at least 3 more guppies with red spots, too. For the females, by the Gravid area (not pregnant) but she looks really fat like pregnant, but she's not. So I'm thinking it might be internal parasites.

I came home from school today to find two more dead guppies, one of them has a red spot, and I don't know if the other one does or not.

This is an established tank, and I've had it for over a year. Almost half of my guppies have died so far, and I really don't want any more to. I am a guppy breeder, and this has NEVER happened before.

Please help me. Do I need treatment, change the water? Just tell me what I need to do. (by the tail)

Awesome to use for internal issues and won't hurt any other fish or crawlers in your tank.

I used this to help with ich and fin problems.
