How to add an anemone safely in a reef tank

[mike31154]

If your tank is already packed with coral that you value & don't want killed, don't get an anemone. Even if it does not move, it will most likely grow & as it does, it will end up encroaching on your coral & sting them.

If you do decide on getting a RBTA, I found the best way to get them to attach to my LR is to rest a piece of eggcrate against them overnight so they can't blow around (I bought mine loose).
Once attached, mine (luckily) stayed where I placed them.
I put them front and center-ish and a bit lower. Out of direct powerhead flow, but enough for good flow. Been almost 3 years now.

In my experience, BTs can still detach from rocks and either kill things or get killed. Even with the best conditions you cant predict their behavior. The safest way is to remove all your coral and put it in with a clown fish, it will settle and once bonded, will rarely move. Then put everything back in. I wouldn't risk it with everything in there.

They like their foot in a crack or hole, I placed mine between a shelf rock and a big rock and it hasn't moved because it can retract into safety if it wants.

They move, my condy walked from one end of the tank to the other. Then it settled for a year, then one day, walked again.

I thought the idea of isolating an anemone on an island was genius and pushed me over the edge of wanting one but being concerned about its wanderings to feeling confident about finally doing it. That was until the RBTA that I had in my tank for about a month decided to hop over from one piece of LR to the next, separated by about 3-4" of sand bed. One day it was on the island where I placed it, the next it was on the mainland moving around hahaha. Maybe I needed more space between the rockwork islands, but in my 35gal shallow reef that was about the best I could do. Fortunately my tank had very little coral in it at the time and its wanderings had little to no impact. Now that it's settled I will consider stocking around it but will still give some space.

Not the answer you're looking for, but...
There are no guarantees of a nem not moving.

I have had one/some in my tank for a couple years.

I recently removed one because it began to wander and killed a bunch of ricordeas.

That being said, a nem hosting clowns is a very cool thing.

Coincidently I've got a couple rbtas at the moment that need to be removed soon.

There you go, that statement pretty well sums it up. As mentioned by more than one responder with experience here, there are no guarantees that an anemone won't move at some point. Might take years, might stay put. You rolls the dice, you takes your chances. If you have valuable coral you don't wish harmed, best to forget about a BTA or start another tank that's dedicated to anemones & clownfish.

Also, while many clownfish may make a variety of anemones their home, certain species of each are natural matches in the wild. A little research there will go a long way. For example, the popular BTA is a natural host to Maroon clownfish. I've had a BTA in my tank since a few months after setting up & have a breeding pair of Maroons calling it their home. The original BTA has split numerous times & the clones have a habit of wandering around. The original stayed on roughly the same perch for years, then decided it was time to make a move. Since the latest move, it has done a great job of killing off some nuisance palys/zoas & a Kenya tree coral that was getting quite large. It also did a number on some montipora caps & my hammer coral. I don't mind too much since I can frag off most of these relatively common corals, but I wouldn't be too happy about having some really high priced sps getting stung to oblivion.

With regard to thinking sand is a barrier, forget it. If a BTA doesn't like where it is, it will simply release altogether & go for a swim until it either ends up in a power head or on another piece of rockwork it likes. A change in water chemistry, temperature, water change and any number of other mishaps can be a catalyst for the anemone to decide it's going for a ride.

Yep. I had one in my 90-gallon SPS tank that didn't move off it's rock for about 4 years even though I moved the rock (and it) around at times. It wasn't on an island, it was part of the rockscape, but always stayed in its rock.

Then I moved it to my 50-gallon tank. It stayed on it's rock for about 6 months, then it walked. Freakin thing did laps around my tank for about a month until finally settling and has stayed put now for about 6 months.
