Interceptor is specific to kill crustaceans, as such it may significantly reduce your pod population and in the majority of the cases will kill any shrimps or crabs in your system including your acropora crabs. Under limited conditions some animals may survive, say a large pistol shrimp hiden under the rock on a slow flow area may receive a less than letal dose but do not count on it.
Basically Yes although there has been reported cases (Me being one of them) were red bugs have resided in some LPS like a torch coral and euphylias (Ancora and frogspawn). If you have those corals examine them well with a good magnifying lens while the polyps are extended. This is important because if they are on LPS a stronger dose wil be required. In my case while all bugs were killed on acros with a dose 1.5 times of the original recommendation of 1 pill per 350 gallons (I used 1.5 per 350 for 12 hours based on Borneman's findings) they kept comming back until I found them on the LPS, in case of the torch and frogspawn I had to treat them out of the aquarium at 10 times that dose for 12 hours to get rid of the bugs, since then about 8 months ago they never reapeared in the tank. The good news is that corals are not afected by the medication so stronger doses can be used outside the tank, really the limitation for the dose is the crustacean population if trating the main tank.
