Tiger Cowrie - Eat SPS?

[blenny90]

I posted this in the Invert Forum - but am posting it here since you all are the SPS experts.

We bought 2 medium size , 1.5" - 2" tiger cowries to help control algae in our 210. Since then, we've got several SPS that seem to be eaten on and last night I saw one of the cowries that now appears to be damaged.

Is it possible that it's the cowries that are causing the damage? Or is this just coinsidence?

I seem to remember reading somewhere that cowries will feed on coral polyps, but im only 95% sure, I could be wrong, someone else will chyme in.

They are Polyp Munchers for sure!

Thanks - I had done a search previously and seemed like most said they were okay. I've got one located and removed. Will have to hunt for the other one tonight.

Thank You - any chance the SPS millipora that was munched on will come back or will it continue to deteriorate?

I'm guessing that it will come back. Get the Polyp Muncher out, make sure it doesn't get any disease. It should recover fine!

I got a tiger cowrie as a hitchhiker and found him eating my star polyps.
