Sun flower

[findingnemo1]

Mine stays open from about an hour after the lights go on which is 9.30 till about 3 or 4. And then they come back out when the lights are off. I feed mine mysis once a week and my tank gets cyclo-peeze daily just a little bit and the sun coral instantly opens when it hits the water. Mine is also in a little cave so it gets a little light but not alot and there is some flow in there.
