I started out with a green bubble tip anemone. I then added a true percula clownfish and a week later added another percula clown. Neither one will host the anemone, is there a trick to this or should i just give it time? Also when i first put my green bubble tip in my tank it bubbled right up and was beautiful. Now it doesn't bubble up at all, is there a trick to bubble tips bubbling? Do water parameters matter?
