Unknown parasite

[Rontheking66]

Hi all

I scrapped a plant today to examine under the microscope as there seems to me some sort of algae on it and I was trying to figure out which type.
When I put it under the microscope I can see little parasites running around.
What are they.
I did have ich in the tank a couple of months ago which was cleared up with a few weeks treatment. The fish are not displaying any flashing or white spots and these seem to look different under the microscope.
Any help is appreciated

Not parasites, just one of many harmless wee critters that are sometimes found in fish tanks. Video doesn’t work properly for me. @Vale! might recognise these ones.

Food for something. Think you'll be shocked at what lives in our aquariums, all manner of creepy crawlies.

You should see what found living on live rock in a reef aquarium, it's it own universe.
