I fed my Trachyphyllia radiata some krill the other day its tenticles had been comming out at night. Now for the past 2 days I have come home from work and checked the tank and its tenticles have not been out in 2 days. Is this normal that once they are fed or full they dont extend them till they are ready to eat again or is it sick? Also is there a good place or book(s) anyone can recommend to learn more about my current corals and future ones? Thanks for your time and help.
