Due to seeing numerous post recently about how to remove anemones and shrooms without hurting them or destroying rock work. I felt like this was in order.

First off, a little back story. Years ago, when I lived in Florida and collected aquatic life on a regular basis, we always had issues with RFA and Warty sea nems being taken off of the rocks safely/ensuring no damage was caused to the foot. Had the same issues with ricordia, as well. As I hate to injure or damage those critters, my brother and I came up with a different way to collect them. We used pipe tied over the critters with fishing line. This worked some of the time, but most times the critters would just crawl to the side of the pipe and back to square one. At this point we pilled sand around the pipe and that really helped get the critters to crawl up the pipe. The issue with that, was tide change. Sand would wash away during this time. While at the hardware store to get some stainless steel screws for rod holders we were adding to the boat, my brother saw some grout sponges and a light bulb went off. He bought all they had lol. The next weekend we meet up to go collecting and he showed me his super idea. Cut a hole in the sponge for the pipe, insert pipe and place over the critter. We would then use rubber bands to fasten the pipe to the rock, pieces of rock, etc. So we tried it. Placed them out first thing in the morning, came back up and fished our usual spots until that afternoon. At that point, they were wet for about 7 hours. When we dove back down, we were amazed that all but one pipe had an RFA at the top. The one just did not want to budge. We removed all of the sponge/pipe combos and have been using them ever since for nem and shroom collection. With this said, I then started to use them to remove BTAs when mine decided to try and take over my tank years ago. Worked like a charm for them. Since then, I have tried to assist other reefers with nem removal by using this method. Best thing about it, NO DAMAGE TO NEM!!!!! It forces them to move on their own. Same applies to shrooms, but you use a shorter pipe of a smaller diameter. So I cannot take full credit for this. The pipe was my idea and the sponge was his. So, much thanks to him years ago for being the smart one lol. (He still is the smart one and works for FWC now and does not have to deal with the Corporate IT world like I do lol)

One note: For BTAs, the pipe needs to be a little longer than you may think. Sometimes BTAs will just stretch and never move their foot. If longer is not an option, placing the pipe sort of sideways always seems to make them crawl and not stretch.

Edit Note: (THX @F i s h y) for tight places or to extend the pipe length to where it may be needed, but space is an issue, use a 45 degree or 90 degree elbow to extend the pipe. The elbow can also be placed on the sponge side for more hard to reach places.

Hope this helps someone and saves a new from having its foot torn and causing damage to it.

Love this method. Learned it from Steve a while back. Have had 100% success.
I would add in tight spaces you can put a 45 on the end. It will add a small bit of length and as @Eagle_Steve said, by have the pipe not straight, the nem moves pretty quickly.

I have found that light colored pipes seem to work better in darker areas of the tank. I had to add a 45 on to the RFA Canon once and after 2 days I still had nothing. Turned the 45 so it was catching light and funneling it down the tube and within 2 hours, I had skirt poking out : )

Brilliant idea. I need to rehome some nems, they started to take over.
Is this the sponge we are talking about? https://www.homedepot.com/p/QEP-7-1...-Washing-Sponge-3-Pack-70005Q-3VP84/203260188 Or something similar?

That is it!!!!! Can be cut down to size if needed. Or you can even use a 2" or 3" piece of pipe to make multiple nems crawl up at once.

Edit: Just be sure that when using a large pipe, it is at an angle, so the light does not shine straight down. The goal is to make them move to the light.

Have you by chance tried this on aiptasia? Curious if this could be THE solution!

I have not. The are NPS, so they would not be moving to get lights. They might move to get in the flow though, so it could be worth a try.

Maybe I missed this how do you get them out of the pipe with out damage. I have to move some mushrooms and RFA.
Gently peel them off. I use an old credit card or a very flexible plastic scraper to nudge the edge of the foot up a bit and then use my finger to gently pry up. They usually let go very easily and the pipe is smooth. This allows for them to gently be peeled off.

Ahh okay they come all the way out . In my mind I thought they would come so far up and stop so the foot was inside the pipe . Have you tried this with baby RFA?
I have. I use 1/2" pipe for them. All of the RFA in the tank below were removed using this method, as I moved all of them from my 180 to this Biocube we setup for my son. Not all with 1/2". Just the small ones. The rest was either 3/4 or 1".

So pretty much any sponge will work?!?
Thanks for sharing....
Make sure it is not one with "antibacterial" or "mold preventing" stuff in it. You want it to be just a plain old sponge.

Nice. I've peeled off thousands with a plastic knife and a bit of time exposed to air, but as you know some of the guys in the deep crevices are difficult. Any idea how well this works for groups of 50-60 nems together on single rocks? Not much space between their feet.
