Ya I like Pete a lot too.
I have kept reidi with a cleaner shrimp with no problems for a few years, so based soley on my experience I would have rated the cleaner shrimp a 1 in the seahorse.org article. But when we wrote that article we looked at thousands of posts from hundreds of keepers. There were many incidents of problems arising from the skunk cleaners. Problems included food aggression (I was not feeding frozen with my reidi skunk combo but it appears to be more predominant of a problem with frozen foods), the cleaning act stressing the seahorses to the point of them going off of food, and aborted pregnancies from a cleaner trying to clean inside the pouch. If it were just one or two people stating such it probably would have been ignored to be honest, but there were multiple reports of the same type of behaviors in many tanks so the cleaners were given a not so advisable rating. There does seem to be some variable with cleaner shrimp involved such as size of tank, size of seahorse, amount of rock work, and amount of feedings, and then some of it is based on the individual attitude of the specimen.
I disagree with Pete on a few other things in the article, as well but Pete and I have always maintained a respect for each other.
The varying opinions on tankmates are often baffling. To read it you would thing people are keeping completely different species of fish. If you follw the progression long enough you start to see some more trends. There are many factors involved IME.
