Hello there! I have been using the "amano" shrimp for some time in my Ahy tanks. There doesnt seem to be any egg stealing going on, for I have not seen any egg reduction! I have witnessed the shrimp, including the crsytal's eating the Ocean Nutrition brine flake when any hits the floor! Sort of odd...Supose they think they tase like chicken? hmmm...Glad im not a shrimp!
