I picked up a zoa rock that had a tiny piece of psammocora (size of a dime) on it with the hopes that it would survive. It has grown out some and appears to be doing great! :smile: I just took it out of the water to scrape off some blue cloves that also came with it but I've never noticed it having tentacles coming out. I wasn't sure if this is a common color morph or not. Either way I'm happy with it. Let me know what you think and if you've seen it before. Thanks.
