Just got my 1st LTA! Put it in my 80G tank and within 5min my peppermint shrimp started trying to pull it's tentacles off! I moved the LTA to my 29 Biocube (with 10min acclimation) and it found a spot and attached thru the sand within 15min right in the front! Awesome! Beautiful anemone and is almost 4" diameter! Love it! Hope my clowns love it too!
