The only ones I've seen split in captivity are Entemacea quadricolor - Bubble Tip (any colour).
I've heard a few claims of Macrodactyla doreensis splitting (Long-Tentacle Anemone) but the ones I've seen have turned out to be Bubble Tips that were misidentified. Many folks confuse the two when the Bubble Tip's tips aren't bubbled - which happens quite frequently.
