I bought two Peppermint Shrimp to deal with an Aiptasia outbreak. At the time of purchase I had a small ( 3" ) pink tipped sand anemone in the tank. The assistant asured me that the shrimp wouldn't bother anything that size so in they went. One week later and all the Aiptasia are gone. Excellent ! Another week later and I was peering into the tank ( lights out) when two ghostly shrimp shapes were spotted marching in single file across the rocks in the direction of the pink tip. Curious to see if they would go around or across the top of it I continued watching. They both stopped and proceeded to pick at the pink tip ! It obviously was in some distress as it curled up into a ball but that didn't bother the shrimps one bit and they continued picking. I shooed them away with my glass scraper but ten minutes later they reappeared and continued dining as before. At the moment I have a moonlight LED shining on the pink tip to deter the shrimps as I can't remove it from it's current location. Does anyone have any tips on how to capture these two Ninjas as so far they have proven to be very adept at slipping the net !
