I've had a RBTA in my last tank and it maybe split 3 or 4 times over the course of 3 years as soon as it became dinner plate sized. My current RBTA that I purchased about 3 years ago now has split at least 25 times since I got it. Anyone have any ideas why? It's great for propagation and selling but I'd like to have one get bigger than 2 inches. They are almost becoming a nuisance and dare I say it's becoming annoying in the way that aiptasia is because they'll start to wander off into my Acros. Attached some pictures.
