Rose Tip anemone sting

[Leadfooted]

I have a pretty large one of these that stays away from my corals when the flow is on. However, when I slow or shut off the flow for feeding, the anemone's tentacles drape down and touch a chalice, Duncan and a few other corals. Does the Rose Tip sting other corals during this short period of no flow? If so what corals can be harmed and what corals seem to get along with the Anemone.

Thank you

in my experience it takes a fairly long time for a RBTA to significantly sting another coral and my bigger concern was a nem footing down over a colony of zoos and snuffing them out. I'd much rather have my nem touching another coral than that same coral to fall onto a chalice or even be parked up too close.

We have RBTA in my wife's tank and it obliterated everything in its path. The sting is powerful to other corals so don't underestimate the nematocysts. I removed one for our reef tank as well, just a slight touch and killed off sections of many stony corals.

That’s interesting.... potency must vary to some degree between specimen.

I have a couple of green in one system and a few Rose/Rainbow in another that so long as they dont park on top of a coral for two or three days do no harm. A passsing blow While they’re on a walkabout has never shown to be a problem.

I'm sure there's different levels of potency for the nematocysts. I wonder what determines it though? Pretty interesting if you think about it, maybe an aggression for competition for space? After many BTA I will never put one back in a full blown reef tank. It unfortunate because I love watching the symbiotic relationship between clownfish and anemones.

Wild bta have a potential to have stronger stings to them. I have heard once aquacultured and split a few times, it can become less. I never lost a coral due to the nem touching a coral for a short period of time but have had lps sting bta tentacles on aquacultured ones

The one in my wife's tank is a monster now! Lol.

I have a standard rose and a rainbow BTA and the rainbow is a kit stickier to touch, not sure if this means the sting is stronger or not.

I had several in my sps tank and they would only kill the part of the coral that it touches a lot. If you have a sps branch that is constantly being brushed by a BTA tentacle that part will die. I never had one go on a rampage and kill everything overnight or anything but anywhere there is contact could sting the coral over time.

Thank you all for the input so far. Here's some pics of my situation (cyano's under control for the moment). The mother nem seems to be happy and has not moved for about a year. It's had a baby which I placed in my sump a while back and now it's had a baby, 2 babies!

Currently the nem will relax down and it's tentacles lay on or touch the Hollywood stunner(I think the chalice stings the rose due to reactions the nem makes at contact. It also hits my Duncan which seems to make the Duncan unhappy and their tentacles stick to each other. There's also a nice golden leptastrea coral and crusting monti that I'm worried about that you can see easily.

The other concern is this is a feeding period (about 10 minutes) when I want corals to be eating, not cringing. For the moment I'm using my baster wand to move the rose anemone's tentacles from other corals during the feeding period but that's not a good permanent plan.
