Antibiotic given to land animals stay there until they poop or pee it out (or metabolized by the liver/ other organ)
Sick anemone will not eat. Almost all antibiotic developed are water soluble. The would enter the anemone easy though diffusion. Give it into the water, it will get into the anemone. If you somehow able to injected antibiotic into the tissue of the anemone, it will just diffuse out to the water. IMO, there is no advantage in getting the antibiotic into the anemone because of the above reason.
+1. If the anemone expands, a majority of the mass is water, which means it's absorbing the antibiotics. Physically feeding the nem will cause it undo stress.
