Hey everyone, quick question about this cabnella. It’s been in my tank for around 2 months now and has at least tripled in size (when it’s open). The tank is fallow due to a brook outbreak, and i recently added a macro algae which has almost completely died off due to lack of nutrients and bad planning on my part. The day after i added the macro, this coral closed up. It’s been 4 days. Any ideas?
