shrimp compatibility?

[reeferious]

i have a mated pair cbs who get first dib at any food, 3 cleaner shrimps that don't clean any fish, a blood shrimp that hides in a cave, 3 peppermints that chew up little aptissa but leave larger ones alone, 6 or 7 sexy shrimps that call a pocillopora their home and a pair of harlequins that i rarely see except when i drop a starfish arm into tank. yes and a pistol paired up with my yellow watchman goby. all these in a 90 gallons and i have rarely see any one of these harassing others except during feeding time.
