May I request some help? I have waterbox peninsula 25 salt water tank, it's 8 weeks old, 2 small clown fish, a few snails, and 4 soft corals (2x zoas, 1 x GSP & 1 small Kenyan ) all doing week until a few days ago. I do 10% water changes weekly. I've noticed one of the zoas doesn't seem quite right. There's something growing in it, the other seems to be popping polyps? I've attached a photo and wondering if anyone can help me identify what's wrong and how I can fix it? Thank you.
