Yeah, please do look for the link. Never heard of another species of peppermint shrimp before or anything like that.
The hydroids are the clear polyps in the picture. It's not the best photo though, I'll see if I can find a better one. Try and get a picture...your description sounds like about 3 or 4 different things.
About the PH placement, I'd not point it at the polyps, but instead try and get another powerhead to create a circulating/crashing motion in your tank. You don't want it blowing at the polyps, that will just irritate them.
