Ritteri anemone deflating when light is on. Why?

[fe342185]

I purchased a riterri anemone 2 weeks ago. Looked great at the store although it was alittle bleached. He is right under a HQI 250w DE 14k halide but after a few hours of light he starts to deflate. He still eats while deflated but every morning when its dark he looks great. There are 4 other anemones in the tank(RBTA) that are all doing fine with acrosleathers and mushrooms. Any ideas? Thanks

Also what do you feed your anemone? Mine only eats small shrimps. Wont eat silversides. Just lets them go. Is it possible its too big? Thanks

It could be chemical warfare between the BTAs and Magnifica. I wouldn't have them in the same system.
