lps not eating

[bluepointreef]

I've had my dendros and tubestreas for about 1 year now. They've grown and flourished. Normally I squirt brine shrimp in the vacinity and their tentacles come out in few minutes and will eat readily when fed directly. However within last month now- they are not 'actively' feeding like they used to. Their tentacles only come out at night? Should I feed them now at night. Similarly, one of my cynarinas and scolymias have been reacting the same way. When a piece of silverside is placed near their tentacles- they normally turn into Jabba the Huts, morph and eat!!! Now they literally just sit there and the fire shrimp pick the silversides off after a while. My water parameters have been stable for a year now. What's up?

How long have you had the fire shrimp? I no longer have any shrimp in my tank because they can damage the lps when they pick off the food. Maybe they are only coming out at night because they are getting annoyed by the shrimp in the day.
