Skunk Cleaner and Pipefish Aggression

[MEGALADON99]

My Banded Pipefish are attacking a Skunk Cleaner i bought at a coral show today. She was preggers which is a plus. I noticed a while after i added her that one of my pipefishes tails were gone completely, now they're harassing the **** out of the Cleaner. I know pipefish are pretty intelligent, so i'm thinking maybe they remember? Or maybe they are trying to eat the eggs right off her. Here's a list of my stock for anyone who has any ideas as to other causes.

x2 Wyoming White Clowns
x1 Bluegreen Chromis
x1 Blue Hippo Tang (1.5 inches)
x1 Moorish Idol
x1 Hawaiian Reef Lobster
x1 Brownband Watchman Goby

I've seen pipefish and the similar clingfish attack cleaners for their eggs.
