Hey,
Why do nems move? I have a nexus joker bubble tip anemone and it seemed great in its placement for two months. Then it split. I thought that it was doing great, or it was doing poorly and needed to split as a means for survival. So I had two side by side, and I thought well cool, all is well, there’s light, a little flow, maybe they’ll someday host some clowns. I ended up getting 3 great clownfish, that are captive bred, but they are not interested in being anemone hosted. I’ve tried all the tricks to get them to seek out the nems, but there captive bred, in a rectangular reef tank with no aggressive fish, they don’t need a nem. I have a superfluous amount of flow in my tank, and the nems only get a fraction of it, so it would be a perfect place for Nemo’s to seek refuge. No luck.. So one day one of the nems moved. And it really decided to cover some distance. Up the aqua scape in very direct light and next to one of my corals. Upon seeing this, I was dismayed, and several hours later, had a small sicce pump out trying to dislodge its hold on the rock. It took me 55 minutes to dislodge my nem, and I also had to switch to a larger Sicce pump. I have a spare return pump, and almost dug that out for my nem foot detachment effort. So that was a month ago. 2nd anemone in original place I presume was happy, but today it went for a walk about. Tomorrow depending on where it ends up, hopefully not in a wavemaker, it will be going to the hospital tank I have going holding its counterpart for now. So why would it decide on relocating itself? I’m to the point I got my corals in there forever spot, and I don’t want any conflict with a nem and a sessile coral having contact. All parameters are good, flow and lighting in nems original place was ideal to accommodate them. I never feed them, light, fish food and phytoplankton/zooplankton are added in tank regularly. What gives?

Sometimes they just move for no reason other than they think they can find a better spot.

A split doesn't mean something bad. Sometimes they produce offspring period. Usually the split will find a different spot.

I was content having them in there original place, I saw them there in my thinking as the lions heads in Indians Jones and the last Crusade. “ Only from a leap from the lions head will he prove his worth” https://images.squarespace-cdn.com/...MSEHYDV1G39RI3GB/image-asset.jpeg?format=750w
I know too much sauce tonight, but thank you for the insight.

Anemones are mobile invertebrates like snails, crabs, and sea stars. I think Reefers have the impression that because they look similar to coral, that they will stay where you put them. This is why I don’t have anemones in my display tank. All too often they will wonder around stinging every coral they touch. But many Reefers have them in their tanks and enjoy them successfully.

Anemones are the cats of the reef. They do what they want, when they want, for whatever reason they want. They don't follow commands, often do what you don't want them to do, and will deliberately do things that cause you stress. BUT, you still love them anyways! :)
Coming from a hobbyist with an anemone dominant reef with close to 100 anemones, 6 different species, currently residing.

I get you all on the nems. I had a few in my first tank, a rose bubble tip that constantly divided, and another type, had longer, skinny Maroonish tentacles that never moved and hosted a pair of Darwin clowns. I loved having that anemone. I tried to get the one out of my current display tank today. I used a small Sicce pump, but the foot was attached in a crevice, and after 10 minutes of hitting with the pump, I gave up. It’s really close to my Looney Tunes Stylocoenelia, so I might need a tip or two on the best way to remove it without hurting it please.
Thank you

They split and move because they are living organisms that do what they please, whether you like the spot they are in or not. It's kind of like telling your fish to only stay on the left side of the tank and remove it from the tank if it moves to the right.
I find that removing them from where they go isn't usually a good outcome for the nems, its best to let it be and do its thing. My nems live within Xenia, leather coral, GSP and zoas without much issue. I have yet to have one fly off into a powerhead.

@OrchidMiss do you know the link or how to build the anemone trap with the foam and PVC tube?

Some, maybe most, anemones will stay put if you put them in a PVC end cap (or some other container) and place them in the sand. I've been doing this for years and it's quiet rare that I've had one move. It does happen, but I'd guess it's less than 1 in 30.

They just do. Personally I no longer keep Anemones, the thought of them wandering around, into power heads, over my corals kept me up at night.
I am starting to feel similarly, less so about the power heads, but with the wondering. I lost all the sps I had in my 110 when they wandered and split everywhere.
I've found that the rainbows wonder much more than the other 2 types I have, a 3rd is on the way, and I can let you know. I'll surely never have a rainbow again. My CSB has stayed put for the last ~7ish months I've had it. This is purely anecdotal, and there is no science or evidence to support my findings lol

Anemones are fascinating and beautiful, but I got over keeping bigger types yrs ago. I favor corals far more than anemones. I do love Maxi-mini though.

I previously had RBTA, switched to chicago for the past 3 years, now have a handful in my tank. They tend to move when they feel there could be better food/light/flow/hiding space; but if they are currently in a great hiding spot the other conditions could be compromised. I have tried a few different anemone nests, so far conch shells are the best to keep them from moving away. After trying natural conch shells, i also 3d print shells mimicking natural ones, seems work similarly good. Now all my nems are kept in one single spot and i have all kinds of corals in the tank without have to worry about getting killed.
