Well, most people were misinformed because there are "fireworms" that eat sps and some other corals, if you don't believe me about this one, I can bust out my zoology book and cite it for ya lol. There is a lot of ocean and a lot of critters in it, the possibilty of random people finding zoa-eating pods is possible, although it may take ideal conditions for these things to happen. For example, just because you have phytoplankton in your tank doesn't mean they will reproduce and turn green, but it happened to my bro. His water was so green that you couldn't see through it, and try it took a 95% water change with 5 hours of light a day to finally take control of the situation. Things happen to some reefers and not others, ya know? sorry to rant, just got on a roll! Being skeptical is good though, because it will force all of us other reefers to get evidence via pictures and testing as well as identifying the potential predator!
