Before you rush to treat, you should realize that the cure may be worse than the so called pest you are attempting to eliminate. Most tanks with sps contain redbugs. In most cases, no notable damage has been definitevely linked to them. People have formed spurious correlations when seeing RTN and then observing redbug and making the assumption that it was caused by the redbug. It wasn't long ago that bristleworms, copepods etc. were thought to be pests and now they are recognized as providing valuable contributions to the biodiversity of the tank. I have had redbugs in my tanks for over two years, ever since I began collecting sps's. They appear to be primarily attracted to only sevreral acropora species. I have yet to observe any damage resulting from their presence. I witness no difference in growth or coloration in the corals most heavily infested by them relative to the other corals. I have yet to find definitive research that shows they are parasitic in nature, i.e., that they draw nutrients from their host. Interceptor on the other hand may be quite dangerous to the tank fauna. Personally, I would not introduce it to the system. I have talked to a number of sps farmers around the area and country and virtually all report redbug with no apparent ill effects. Just my two cents but something to consider. Many will undoubtedly disagree.
