Black bugs. Like red, but black?

[Aquattro]

So I picked up a frag today, and per routine, I have a look under the microscope. There are many little bugs running around that look very much like reg bugs, but beige and black. They also have antennae. They move around a lot more, but are crawling into the polyp cavities.
Currently dipping in some Interceptor, which I'm sure will remove them, but has anyone seen these before?

I have talked to a few people who have had black bugs before and used interceptor to treat them, not sure if they are the same as what you have because I never saw them though.

I had some, they liked my monti's, nuked them and tank w interceptor, seemed to work fine, did lose some crabs that i couldnt find/take out before treatment.

I saw those on a monti frag once also. I didn't know about interceptor (or much of anything else) at the time, so I freaked out and just threw the frag in the trash.
