you can try salt bath treament when transfering the fish to a quarantine tank,this treatment, is less stressful and seems to jumpstart the immune system,seachem makes some meds; follow directions;lots of water changes and remedicate.. hope this helps..chillin

Thanks! Salt baths were what I did when this all started. And I kept the hospial tank with higher salt too, but that didn't help.
Looks like it is parasite thing, but nobody can be sure. The symptoms are just so similar.
How often and how big water changes? I currently do 20% every 3 days.
And I add 1 table spoon salt per 5 g. I think that did affected some of my plants already, but I hope they will grow again after all that nightmare ends.

A little bit of update.
I have no new sick fish since Monday. But 2 of the endlers do try to scratch at plants every now and then. Not too often, but it happens.
The guy that treats the fish in the store I got the sick guppy said they treat them with sufla and it is safe for shrimps. I saw that the medicated food contains sulfa too, so maybe that saves the remaining fish. It did not help in the hospital tank, but maybe it was too late for them.
There is a chance this thing is parasite too.

So, I see these approaches:
1. What I am doing right now - 20% water change every 3-4 days adding 1 tablespoon of salt per 5 g. No idea if that helps, but I am about to loose the moneyworth plant already, it lost lots of leaves, but is not melting yet.

2. Treat the tank with sulfa or some other anti-bacterial medicine like Quick Sure (is supposed to be safe for shrimps) or ParaGuard (nobody can really say if it is safe for shrimps)

3. Get the shrimps out (that's gonna be a pain, but I can get the bigger ones at least) and treat the tank, but again treat with anti-bacterial or anti-parasite medication.

Any advice or comment will be very much appreciated!
Thanks a lot!

Hey, Infrareddream. I have some Quick Cure if you'd like to try it. I don't think it's usual for endlers to scratch at plants (but they like to poke around for food).

It sounds like your tank situation is stabilizing.

Thanks Morainy, maybe Quick Cure is what I should do to make sure it is all clear. I think (want to believe) they scratch less these last 2 days then they did, but can't be really sure.
I wonder if Quick Cure will help to clean parasite AND bacteria as nobody can't really say what is bugging them.

I hope HOPE you're right and it is stabilizing. I know that I am almost starting to enjoy that tank again. Just still afraid. I don't want to see any clamped fins ever again!

Yes, this is what I started it, but it did not help.

It's been a week since the last sick fish, I so much HOPE this is all behind us.
But I still wonder what is it the way to make sure the tank is clean?
The remaining fish had anti-bacteria food for almost 2 weeks. Maybe that helped them, but can the bacteria still be in the water?
