Anemone lesions - is this bad??
Hello
About a week ago we introduced a BTA into our tank. All has been going well until today when we noticed what look like lesions or small holes on the anemone. It looks like internal organs are protruding from the lesions. The tank parameters are good - no nitrates, nitrites, ammonia, and our salinity is spot on (35). The BTA has not yet bound itself to a spot, and so has been moving about the tank, so we have considered that it might have torn its skin. Tank mates include hermit crabs, clownfish, cardinal fish, peppermint shrimp, snails, and a blenny. So we do not think it is being predated on (?). Can someone help diagnose what is happening to the BTA? It was mostly inflated throughout the day, but it does not look as healthy as it did. On the plus side, it ate some shrimp tonight. Thanks for your thoughts - all ideas are most welcome!! |

To Reef Central I've never seen spots like that. You might be right about it being a lesion. If so, that's likely a bad sign. Has it been eating?

Looks like small tears. Might heal if it is otherwise healthy but it's not a good sign that it won't attach.

They appear to be mesenterial filaments, typically exposed when an anemone is forcibly removed from a rock. It also appears to be bleached. Check your water parameters and keep them stable. It should recover given enough time, as long as it does not become infected. |

People have also had no issues with them so I would just be careful. |

------- Thanks for the response. Regarding eating, it has eaten twice since we saw the lesions and seemed to take food as usual. But, interestingly, it has completely collapsed twice like we had not seen before, and then rebounded later to fully inflate. It appears to be on its "last legs", but not having had a BTA before we have no point of reference. |

If you could post picture updates of the anemone, it may help people make suggestions as they may have had similar experience. If it is really dead, then it will physically come apart and melt. Until then there is a chance of recovery. |

Here are a couple new photos from this morning. It moved during the night, and the "tears" have progressed so that more of the filaments have come out. You can see the larger volume in the attached photos. We will double check the water parameters - I did not notice that it might be bleached, so thanks for pointing that out. The rocks are pretty rough in some areas in the tank, so wondering if it might have snagged itself somehow? Although it would seem that they would have evolved away from that happening over the past millennia.... The shrimp and clownfish steal food from the anemone, but we have not seen aggressive nipping or anything like that. Thanks for the insights, everyone. |

Sorry for double-posting this morning, but here are the photos I forgot to attach to earlier post.

Looks like you'll end up losing that one.

If you can get or diy a containment for the bta, I would do that. Basically a decently sized plastic container would work. Drill a bunch of holes in the sides to allow good water flow and secure the container in a top corner of the tank away from direct light. I would inspect the tank about two hours after lights out or if you happen to be awake in the middle of the night. If you have live rock/ rocks from coral purchases, you may have a hitchhiker you have not seen during the day. Or the peppermint. |

Also, how old is your tank? The rocks, sand, and back glass look really clean.

I once had an LTA that had similar issues, and while watching it and lifting to get a good look I saw a group of huge bristle or fireworms, like 2 feet long.
I trapped the worms, and I'm not sure if they were the cause or just a secondary issue, that LTA did not make it, but the Malu I placed in the same spot had no issues. Both nems were perfectly fine on intro.

Today the anemone actually looks better than it has for several weeks - the tips are more inflated and it is inflated more than in many many days. The side still looks terrible, but its behavior / vigor is improved. Not dead yet! |
