You mean asterina starfish

A few months back, many of the zoo frags we got shrivelled up and died. We found the same link to the asterina starfish, and did an iodine dip on the remaining frags and on the colony that also seemed to be going downhill. We also too the reef apart and found about 30 asterinas on about 85 lbs of LR. All that we found, we killed.

Anyway, we also changed the circulation in the tank when we put it back together, increasing the flow to the zoos areas. Haven't lost any zoos since then. However, we still see asterinas from time to time. They don't seem to be near the zoos when we find them, so I'm thinking the lack of proper circulation to the zoos was the culprit in our case.

How's the flow in your tank, Danny?

Well, the flow to the very top and bottom of the tank is good. 4 powerheads create flow to the SPS up top, and my return comes from a spray bar across the length of the bottom back of the tank. All of my zoos are in the middle regions of the rockwork and get residual flow from the various pumps.

I have one aternina star that is quite a bit larger (1") than the rest. I wondered how it could have grown so big?

Maybe it's a different species than the rest and could be your culprit. Mine are all about 1/4", give or take. All seem to be oddly shaped and are kind of a light-grey-white colour.

My "reef safe" golden spotted rabbit ate all my zoos.....after he'd been in the tank with them for a while....he also liked to take chunks off my yellow toadstool and my kenya trees and it eats my GSP covered rock quite often so it looks all scraggly then it grows back and it makes short work of it again, so I think your rabbit would be to blame...I can't put anything in the tank except the button polyp colony that has been in there for a long time and is pretty bland...

Thanks for all your help. I suspected the rabbit fish but have never actually seen it nip at anything. I did pull out a few stars and even a Foraminiferan (I think). I'll have to work on catching the rabbit fish next, hopefully I can find it a new home.

Hey Danny, what is the species name of that fish ? I can't find much using that common name.
