Think I am going to loose my 3 L260's to some form of slime

[powerfulpumpkins]

Since buying a third L260 Queen Arabesque they have all come down with some form of white slime/covering to their skin.
I noticed it start on one so I tried to cure with Malafix which didnt work-stopped it a little but didnt cure. I then tried Waterlife Protozin at half strength as I didnt know if it was safe for plecs. This didnt work- but then I heard a friend used a half dose on their L260'S and killed them ?
I then tried Waterlife Myxazin first at half dose then full dose but with no cure. I am now trying a Meth Blue 24 hour dip which is what a local store suggested.
My ph is 7 temp is 28 and no nitrites, I cleaned the filter today to see if that also helped.
I am clutching at straws now does anyone know a safe suitable treatment or what my fish could be suffering from.
Thanks

At the top of the forum here there's a post that asks for a full list of information. Could you please provide that for us? It will make you have a much better shot at getting information that might actually help with your problem.

IMO, you should NEVER treat with the shotgun approach like you have been. Figuring out what the problem is needs to be first and foremost, so you know what to effectively treat it with. Can you get pictures? Did you quarantine the new addition? Most of the medications that people use have a certain amount of toxicity in themselves, let alone when you combine them into a chemical soup for the fish to then breathe. Methylene blue will be effectively killing back your biological bacteria in your filter, if the other stuff you'd already added haven't. That means you'll need to be especially careful with not overfeeding and doing extra water changes once you diagnose what the problem actually is and how to treat it.

When you say white slime, do you mean thickened slime that's sloughing off in patches? Cream colored sprinklings of varying sizes that are thicker on their abdomens? I'd honestly love to help, I just haven't a clue where to start, I'm sorry.

Have they got white patches in random places on their bodies. If yes then i have just experienced this disease and unfortunately it wiped out a good few of my fish before i had it under control. I lost a megladoras, a juruense cat, two uarus, and about 10 characins of various types. My mistake was treating for white spot which must have been a secondry infection. Check fins for redness.
My finnally successful treatment involved treating initially with melafix, and then doing 20% water changes whilst treating full dose protazin for appx two weeks solid.
This eventually cured the problem although afterwards it occured to me that the clean water everyday probably did the most work, with the fish rebuilding their imune system. I traced the problem down to some rotting prawn hiding wedged under some bogwood, that has taught me never to get slack with the maintenance again.
I have an adonis plec, a blue eye and a royal panaque in this very tank, they were not affected badly by the protazin or the disease.

Barbie sorry if my post didnt cover all that it should have but at gone 2am when I wrote it I really should have been asleep but I wanted to post something to get alittle feedback.
I didnt treat the L260'S with a shotgun approach. I ID'ed what appeared to be slime on the plecs so I treated with a product which treated slime diseases- seems reasonable to me. When my LFS suggested a Meth Blue treatment this was carried out in a small quarentine tank (only spare tank I have)so has not affected my filtration. Things have moved on now and the slime seems to have been a secondary problem to a much bigger problem I have only just uncovered which I will post about in another thread.
