I'm so excited. I have had zoa colonies dissolving before my eyes while others thrived. I thought the amphipods I saw on them were just eating the dying polyps but then I read that they may be the cause. Then my savior arrived when I finally moved my yellow coris wrasse from the quarantine to the main tank. 24 hours later every single polyp in my tank is open and I see zilcho amphipods climbing on my zoas. Hooray yellow coris wrasse. Sorry had to share my excitement with someone...LOL
