do i have red bugs?

Can you remove one of the affected corals and give it a medicated dip? You can dip and then check for parasites. Red bugs won't come off with the usually medicated dips (you need Interceptor), though you should be able to easily see them with bare eyes when the coral is out of the water right under your nose. Usually if it is a parasite the coral will brown out before it gets to the point of recession though.

As time goes on, you will learn what corals look like when they are infested with parasites and if they look that way and no red bugs are seen it can often be AEFW (Acropora Eating FlatWorms) which can be a nightmare.

I sure hope that if you're not quarantining corals that you're at least giving them a medicated dip (I like Coral Rx), and an Interceptor bath if you have Acros. If not, you're just asking for trouble and it will show up eventually.
