i was told peppermint shrimp are a hit or miss when it comes to eating aiptasia, mines literally devour them within a week of putting them in my reef..not one in sight, so i started feeding them mysis and man they love it..shrimp on shrimp love lololol also never seen this but they litteraly crawl all over my hand when i try moving around some corals, i could just hover the tip of my finger above the water and they swim all the way to the top, literally half their body out of the water just to get on my hand.. wth :/ oh well all i know is that they are super healthy and thriving day and night all over my nano
