LPS vs Coral banded shrimp

[Tippfish]

My acans and trumpets look terrible as well as zoas. Could the coral banded shrimp be guilty?

If you feed your LPS there is a good chance that the Coral Banded Shrimp (CBS) has caught on to it and might reach into the coral and try to remove the food. There is also a chance that it likes the fleshy polyps of the coral. I've had peppermint shrimp do it - so I wouldn't put it past the CBS.

I had CBS with LPS and never an issue. It was mean with other shrimps though.

I have a pair of cbs in my tank which is full of lps and I don't have a issue with growth or tissue recession. They will take the food out of the lps but I've never seen them damage a coral. Have you got some photos of the effected corals

What are your water parameters?

+1 specifically no3 and po4

Doubt the shrimp is the problem. Would guess something related to water params

Are your parameters constant? Did you acclimate them to the light? Are the zoa's wild colonies?

I had a zoa frag for a few weeks without problems but out of nowhere it stopped opening up and after a few weeks I just discarded it. All other zoas did very well. No idea what happened...
