There are two forms, or types of quadricolor. A smaller colonial variety that obviously splits, and a larger solitary variety that may not split. You may have the solitary form, and no matter what you do, it may never split.

" As a rule, in shallow water (e.g. on tops of reefs) polyps small (oral disc diameter 50 mm), clustered together in crevices or adjacent on coral branches, so that tentacles are confluent, forming extensive field; in deep water (e.g. on reef slopes) polyps solitary, large (to 400 mm diameter), with base anchored in deep hole."

I have been trying to get mine to split as well. When you say large volume water change what would be the precentages for those two water changes?

It depends on how often/much you change your water now. If you change your water fairly frequently (like weekly or twice a month), then a larger water change is necessary (like a 30-40% water change, but IMO, at least 3x your normal volume). If you have become lazy over the years like me (down to a 10% water change every 6-8 weeks, and sometimes longer), then doubling my water change volume and doing a second water change after a week will generally cause some of my clones to split.
With a single, large BTA that I had for a while without splitting, my plan would be to feed 3 times a week for a month, with no water changes, then do a 25% water change followed a week later by another 25% water change.

This is my experience also. I have a rather large RBTA and have had it in various tanks for many years. The only way I've gotten another one is by manually cutting it. I've given self made clones to others. I also had it in a 29 gallon tank under PC's for a couple years. I tried no skimmer, no water changes, huge 75% water changes, never split. I've seen it bubbled, shrink, expand, walk, stay put, high flow, low flow, lots of food, no food, you name it. To this day, it has never split on its own. It's now in a much bigger tank than it ever has been in before, and just as happy and stable as ever. Never splits. I agree, I think there are two types.

I did a water change last week about 10 gal and just did another one today about 14 gal I can't do anymore then that amount because I have some corals on the top of my rocks and it would expose them if I took anymore water out. I had been feeding it 3x a week then I stopped and feed about once a week only 1/2 silverside so I will try jumbe shrimp cut up and more frequently and see if it will split. Water changes r being down 2x a month but trying to get my nitrates down they r kind of high right now.
Thanks
Thanks
???? Who told you that your corals can not be out of water?
For the amount of time a water change should take, you're not going to have a problem!

No one told me I did not think the the finger leathers could be out of water or the monti / plate corals can't remember their correct name.
good to know. thanks for the info.

RBTA split when they are under stress to improve the chances of survival.
I had two RBTA for over a year and they were healthy, well fed and got fairly large. During that time they never split. One night the timer that ran my 400W MH light stayed on and the tank got blasted with light for 24 hours straight. When I came back the next day I noticed the RBTAs had moved and split. Now I had Four. About a month later I upgraded to LEDs and during the first week with them Two of the RBTAs split again. I raised the fixtures up a little and shortened the on time by an hour. There are now six healthy RBTAs in the aquarium with one GBTA.

Wow a 400w MH i thought that would have cooked them leaving it on that long..
