Hi everyone! I have a question about my red mushroom coral... It's been shriveled lately. My tank is about 12 weeks old and it has this coral, a star polyp, a digitada coral, and several miscellaneous buttons. Every coral except for this one is doing extremely well! My star polyp has grown onto the rock so it's considerably bigger than it was when I got it. The digitada is fuzzy with extended polyps and very healthy. The buttons open up completely and eat rotifers everyday, so they are healthy too. But, my red mushroom has been shriveled lately. For a few weeks it was doing great and opening up super big and now it doesn't open up much at all. Tank specs: 92 gallon corner, calcium-450, KH-10, salinity-1.026, phosphates- <1ppm (I had some dead rock so that spiked. But it goes down a lot with each water change. Plus the mushroom was fine when this was higher.), ammonia, nitrite, nitrate-0, ph-8.3. Its base has been spreading this entire time so I'm wondering if it is just doing this to reproduce? It has been kept in the same spot. I run metal halides, blue actinics, and LEDs at night. Any help would be greatly appreciated!!! Thanks! P.S. I have a canary wrasse, a royal gramma, 2 ocellaris clowns, and a tomini tang. None ever touch it.
