Discus Parasite

[joricano]

Check your live blackworm containers to see if they are there as well. These may be from the water the worms are in.

Nope not there. These things must've come with the feces.

So does anyone know what this is? I've searched high and low on the internet and Untergasser's Handbook of fish diseases but could not figure out what this parasite is and how to kill it.

I've tried Levamisole and Flubendezole(Kusuri Wormer Plus) but can't seem to kill it.

This looks a lot like a fluke which include Gyrodactylus and Dactylogyrus. These are skin and gill parasites, not GI parasites. Alternatively, it could be one of the small worms that inhabit all tanks and collect on fish poop soon after it hits the tank bottom. It is not likely the cause of your fish's lack of appetite unless the skin or gills are heavily infected. A few of these on the skin or gills will not cause significant problems for the fish. You can youtube how to do skin scrapings and gill biopsies in order to rule out the possibility of disease from these. I applaud you for using a microscope, but to consider GI parasites, it is crucial to catch the poop before it hits the tank bottom. I know from personal experience that after it hits the bottom of the tank within minutes all manner of critters will start munching on the poop and it will be difficult to identify true parasites. See the Fish Doctor's brief comments and video of this:

I would encourage you to look for Cryptobia iubilans in fresh poop. I have posted several times on this and posted videos of it. There are also YouTube videos of Cryptobia. At the 2018 NADA meeting vet Dr. Stephen Smith stated Cryptobia was one of the most common, if not the most common, causes of chronic wasting disease in discus. It will not respond to Levamisole, Flubendazole, nor metronidazole.

I searched for Gyrodactylus and Dactylogyrus and it' not it. It doesn't have the "whiskers" or the "V" on one end. I've seen the Gyrodactylus once but i have not seen it in my recent samples.

This thing looks flat(blob like almost) and i've been treating with General Cure and i seem to find less and less of this (whatever it is). I'll try to do some skin scrapings to see if they are there.

So i looked in Youtube and this is what i found when i searched Cryptobia

So these along with the worm(or whatever it is) was present in the poop. i treated the fish with Metro for 10 days then i let it rest. When i looked at the poop the cryptobia(assuming the post in youtube is correct) was gone. What was left was this Fluke/worm blob.

This is a better video of Cryptobia. It was made and posted by a vet. The twirling motion is characteristic.

Here's my video.
