Marine Mite?? Is this bad?? Help me identify this. Microscope pics

[alindell]

To the naked eye these are about the size on a pin head and look like a black spec. I have seen these guys crawling around the base of corals sometimes on the flesh of a coral like a zoa or Monti. I have had black bugs before and these are not black bugs. Black bugs died fast in interceptor and they hurt the coral... these guys survived interceptor and the corals improved and have done better. Under the microscope you can tell the difference between parasitic pod and this guy.

They differ from the parasitic coppepod look. These have I believe 8 to legs and appear to be some sort of mite. I have tried a variety of treatments to kill them and nothing has worked. They are like impossible to kill.
Are these bad most important question and what are they?
How do I kill them if they are?
Am I worrying too much? Lol

Hey, I’m not sure what this is, but I’m having trouble seeing the videos!

 

[alindell]

Anyone else having problems seeing what this is?

 

[alindell]

Are these guys bad?

 

[rayadog]

What are they found on, predominantly?

What are they found on, predominantly?

Everything zoa's, SPS, lps. Not usually on the tissue but the rock

 

[alindell]

Sometimes they crawl on the zoa tissue

Halacarid mite, in my experience they don’t bother healthy coral, but you can get rid of them with ivermectin in a separate designated med tank.

Yeah, definitely marine mites. They're most likely neutral for most tanks, but there's a small chance they may be harmful or helpful:

Not yet, unfortunately - marine mites haven't been very common hitchhikers for me to ID, and there are a lot of species, so I'm not very well versed in them yet. I know there are a handful of parasitic marine mite species (including some parasitic on sponges or other inverts; to my understanding, most are predatory to smaller critters, some are algae-eaters, and a small group are parasites), but I don't know of any species that parasitize corals specifically.

The idea of these being more opportunistically predatory toward dying corals is also plausible, but I can't confirm one way or another at this point.

What's the dosage? Procedure? Elaborate. Is ivermectin similar to interceptor? I've done an experiment to see if these mites would die from like a 10x dose of it in a tank. I put one large 23 mg pill of milbe oxyime or interceptor in a 20 gallon tank with them and they survived???? Is ivermectin a different thing that will kill them?

In what ways can they be bad. I think they bother zoas. Is there an in tank treatment that wipes these suckers out?
