I had a thread about my wonderful Green Pocillipora, which grew from golf ball to Soft ball size that mysteriously began shedding polyps and now is basically a skeleton. Now my Valydia, which grew from about 3cm to a nice sized colony, is showing signs that's freaking me out! Everything else, coral, params, etc. are fine! Any ideas? Is this just new growth? 'cause it never looked like this before.
