The first step in having a healthy Entacmea in your tank is the wharehouse you deal with ! And this is what Incredible Aquarium does: they provide healthy specimens !! No rips, no damaged tentacles, no bleaching, no gaping mouths, no holes below foot... no bacterial infections of stomach... Getting them to eat after the initial 24 hours in your tank is a piece o' cake.
