Impulse Anemone Purchase


Active Member
Ok, my friend, (yes, there really is a friend) purchased a 2-3" Sebae anemone to go in his Nanocube 12g, for the pair of ocel clowns, I assume.
The tank has 48w of PC lighting. Not sure about water parameters, I will beat him up over those.
I am no anemone expert myself, so I'm looking for advice to assist him on this experiment.
What are the feeding requirements of a Sebae?
Any special testing requirements?
What are the signs of danger?
Thanks guys.
