Danios wasting away

[Tall Len]

At wits end with this. Hope someone can help!
Have a 29gal tank with Glofish (zebra danios). 5 adults (started with 9) and about 8 fry.

The tank is four or five months old and cycled. I've tested the water. 0ammonia, 0nitrite, very little nitrate. I do, at least, a 20% water change weekly.

They appear healthy, active, swimming and eating normaly, but are slowly dieing off. They get thinner and thinner, where they look like concentration camp victims... after about a week, they are weak, and mostly just heads and tails, no meat on them and then die.

I've tried treating with epsom salts. From all the reading I"ve done online, I am pretty sure it is an internal parasite/worm, but nothing is visible externally. Even their poop looks normal.

I've lost 4 or my original adults and numerous fry over the past couple of months.

The only thing that I think is responsible is that I introduced some java moss and have a bad outbreak of snails the last two months.

If anyone can help me with a way to stop the die off, I'd be greatful. The searching I've done seems to end badly, with the tank wiped out and bleaching it and starting over. There was a thread on google where someone used pig dewormer and saved his tank... but not sure...

Please help

I'm woefully inexperienced with disease, so research this. For discus parisites we use metronidazole, flubendazole and praziquantel. Some can be mixed in the food and fed to the fish, a very effective way of getting the medicine to the problem. Do some searches for those meds, how to use for small fish and where to purchase. Some shops sell praziquantel in the brand name Prazipro.

So it's just the adults that this is affecting?

How old are the fry?

No, not just the fry.
Lost about half the adults and half the fry to it.

Looks like another of the adults has it (probably won't last a week)
and two more of the fry.

It is a slow killer... I've been losing about one every two weeks.

I did try Prazipo this week. Dosed the tank as directed. Waited three days and dosed again. For the week, I soaked food in it and fed them that (various dry foods and frozen blood worms). As I posted above, it still looks like one of the adults and two of the fry have "it" and are getting thinner.
Anything else I can try?
Maybe the Prazipo worked and these deaths will be the last?

Prazi only works on flukes and tapeworms (cestodes), not internal nematodes (capilleria). Treat with Levamisole in water or Fenbendazole in food. From what I understand, the levamisole treatment is hard on fish, snails, and shrimp, but the fenbendazole in the food does not seem to have any bad side effects. You can buy fenbendazole flakes from AngelsPlus. (I'm not sure if your Danios have nematodes, but if you've ruled out bacterial, it is probably worth a try).

Any idea where to get Levamisole? That was the successful treatment I found searching the web, but my vet didn't carry it and had no idea who would?
