How to make a rose anemone split?

[hipertec]

I have two rose amemones in my nano tank. Their getting really big (6-8 inches expanded).

Is there a way to try to make the anemone split? Not sure if irritating them will help or?

Clean water and good light. I started with one and have between 60 -100. I did nothing.

IMHO it depends on the anemone. I've had RBTA's that got huge and never seemed to want to split. On the other hand, I currently have a family of RBTA's that get to be about the size of a egg and then split. I bought a rock with 9 of these on it and in under a year I was up to 25.

Most of the time, if kept healthy and happy, they will split eventually if not frequently.

I've had good luck forcing splits by introducing (mostly harmless) changes, most effectively feeding changes. If you spot feed heavily on a daily basis for a week or two, and then totally cease feeding, you will often get a split within a week or two.

I'm not sure I'd encourage a split. Let mother nature sort it out. I've started with one in a 29 gallon bio-cube and now have 6 I don't want them to split and honestly find it more of a curse than a gift. The original was large and started to outgrow the 29 gallon. Then after the split in the course of a couple months two "really" outgrew the cube and forced me to upgrade to a 40 breeder. Overtime a split here, split there, and now I am at 6. Again, too crowded.

Sell them or give away - sure. However, one can damage the foot if not careful so I just leave them be. Originally mine split, or so I believe, because I was feeding too much. I was feeding silversides which many say are bad (and I agree). After some research and what not I stopped feeding all together and let them get what they catch or the clowns give them. Over the last say 8 or 9 years I am at a total of 6. I had 7 at one point but this one kept moving due to space issues I'd wager and got caught up in between my hammers. It ended up dead - I never saw it until it was too late...

So no - I'm not a fan of trying to force nor like it when they do! But I'm sure I'm a minority

I'm with you. They have been a pain off and on.

Killed a few SPS crowding it for light.

If its in a nano maybe do a big water change. Like 50% or more. You could also turn off the lights for a day and it'll move out of its current spot so you can cut it yourself

I bet. I sure hope I don't end up with has many as you noted. I would be going crazy. Then again, maybe they can duke it out with the Xenia I have that is starting to go crazy. The joy of soft and LPS tanks.

And to think I'm upgrading to 240 gallons because of the little anemones.

Personally don't do any of that. Just let them roll on. You will get more in due time. If it is expanding, not losing coral, and looks healthy then why punish it or any other tank mates trying to get it to do something it maybe isn't ready or willing? Some argue that splitting is a sign of stress, duress, and they are doing it to continue on with life. Others say it is a false statement.

Edit: Just caught the cut bit. Above all there is no need for that. Many die in the process especially if it isn't something you have done before. They are so cheap I don't see a need.

I agree with it not trying to split it if necessary, but in a nano tank, I understand why he would want to split it. Stinging corals, moving around everywhere, and overall causing havoc will eventually make you want it to split or get a smaller one. I burned some corals pretty bad because of nems in my nano and eventually had to move it back to my big tank. But nems aren't even supposed to be in a smaller tank because of how big they get, so splitting or rehoming it will have to be an option eventually

I wouldn't routinely (or ever) try to get one to split in a display After splitting it's common for one or both to take a walk, which can be problematic.

The stress-feed technique came in handy 15ish years ago when the rose color variation was first popular in my area, and they were selling in LFSs for $200-300 a pop. That was good motivation to learn to force splits.
