I have 2 of them in tank. One is stationary and the other has started moving, as a matter of fact, I cant find it! I havent noticed any multiplying, though
it looks like it i have found that if you can take a pice of rock and sit it on top of it that it will alot of the time move to the rock to get light after it moves to the rock take it out of the tank and but table salt on it and it will fall off the rock and then you can put the rock back in your tank.

if the move around. the actual anemone moves to another spot then its more than likely a manjanoe anemone rather than a apista. both spread fairly quick but apista is stationary/
