Sounds like you have camel shrimp, which look very similar to peppermints, but are not coral safe.

I don't consider peppermint shrimp coral safe anymore. I've seen many destroy LPS in my own tank. I don't think they eat coral, but are trying to get to the food the coral has eaten. A problem is that there are at least 6 species of shrimp that are sold as "peppermint shrimp" and difficult to tell a part. My guess is that some species are more prone to eat aptasia or mess with corals than others. There is a nice image of the different types of peppermints on page 196 of this paper on peppermint shrimp.

However, I've never seen a peppermint kill zoanthids and it just so happened to appear that they started doing damage to his newly purchased zoa rock. There is a very good chance that the shrimp are just picking at dead coral flesh and the real killer are zoanthid eating nudibranch and/or spiders that were in the rock. I've purchased larger zoa colonies from fish stores and the rocks were loaded with zoa eating pests, even after QT and multiple dipping. Depending on the size and type of the rock, you can dip them for days and never kill them all. Hopefully that's not the case.

So it sounds like I better get rid of my peppermint before I get started on my zoa tank... are there any other shrimps that would be safe? I was thinking about a fire shrimp.

It actually killed off two colonies that were already there but the last straw was the new $100 zoa rock I bought. I dip everything to be safe. These guys went straight for the zoas everywhere. They got them and the plate coral.

I have a fire shrimp also. Not very visible until feeding time but he doesn't touch my coral.

Definitely no peppermint shrimp for me. Or carpet anemones, I read posts by several people who have had them get anemone ate there fish or were badly damaged by one.

TreyC2010 · Aug 21, 2015

That's good to know. I'll stay away from them for sure

Can't they just all get along. Lol that's why I love this site, there is always someone who has had an experience with what ever you may be going through.

Yes i Just ask for cheap unflavored (no hickory or honey stuff like that) and have it thick cut..

I have never seen a true peppermint shrimp eat healthy corals or zoa. if you have corals that may not be doing well, then anything may go after them. Also if you do not feed the tank enough then who knows what will eat what. I have a 4" long Coral Beauty dwarf angel that picked at some corals that had dying tissue and I have 6 peppermint shrimp that have never gone after corals. once my corals settled down and were healthy the angel never bothered again. I hope your problem is the shrimp and not tissue necrosis.

mine picks on my lps, not zoa though. Pretty soon they are going to convert my tank into full SPS tank lol. But I dont want to see any of those aptasias ever again in my dt, so i guess the lps are going down with them.
