how fast do anemones grow?
 

mainly BTA and Sebae anemones, how fast do they grow and at what point do they split?

thanks

Lot of it depends on how often you feed,they grow pretty fast like going from a 3'' to 7'' in about 5 months. Mine have split once they reach the 7 to 8'' size. Started with three 5 months ago now i have 6.

A BTA can split on arrival from stress alone, or can be induced by over feeding.
I've had my sebae over 5yrs now, no split, and not sure if they even do split.
Growth depends on food/light/water params.
Mines about 22"
