Bubble tip anemone expelling Zooxanthellae daily

[Embdaw]

Our GBTA went from being a gorgeous green to a pinky/brown since we've had it. It was a really murky brown for a while, but then started expelling Zooxanthellae every day and lightened up to a rose pink with brown. Also, we've had it about 4 months and it hasn't grown at all. It is about the size of a 1/2 dollar fully open. It gets fed Mysis Shrimp 2x a week. Any ideas why it is doing this or how we can get it to stop?

Running a biocube 29 with stock lighting. Day Lights are on 7hrs, moonlight 2hrs. PH 8.2 Ammonia/nitrate/nitrite 0. Salinity 1.025

Possibly Looks like it doesn't have enough lighting. I say that because I have a bunch of GBTA and at one point I hadn't changed the t5's in about two years. It went from green to brown.

I switched to new lighting and back to a deep, vibrant green they have become.
