Hey reeefers. i am new at this my tanks been up only for 3 months. I got a bubble coral about 2-3 weeks ago and i notice it half closed. Basically once i first got it, it fully openned up and then it was good for 2 weeks. and i just notice for the past 2-3 days half of it hasn't been openning up. I've been direct feeding them on a daily basis with cyclopee. It also has been spitting out some brown slimy stuff. is this normal? Any advice would help. thanks in advance.
