well, I wouldn't say that is the case. For instance your RBTA split due to stress in your tank. It's probably a survival response where it's saying "uh oh! I better split so maybe one of me survives!!"
Can't really say what, if any, long term possibilites are, but the health of your animals should be the main concern. Anemones usually require established systems for long term survivability and don't usually tolerate poor water conditions.
