See, I'm of the the opinion that this is all a big hoax. All you've proved to me is that you're in on it.
In 10 years in the hobby and easily 30-40 peppermint shrimp over the years, not one, not a one of them ever ate an aiptasia for me.
Those ones are worth a king's ransom if you ask me!
Now if only someone could do a demonstration of some emerald crabs eating valonia, I'd pay another king's ransom for those ones. Another so-called "sure thing" that never worked as advertised for me.
Stupid critters mustn't read the forums so they don't know what they're supposed to do..
