Sorry your anemone didn't make it. LTAs just don't seem to recover from tears in the foot. It would be interesting to see if antibiotics might help in those cases, I'm not sure if that has been documented by anyone on here. For future reference, Entacmaea quadricolor, bubble tip or bulb anemones, as they are called is a good first choice. They are much hardier and a tear will usually heal with that species.
