actually a carpet anenome, but you need proper lighting, speaking of which how old is the tank lighting flow ect ? do you have sps or lps in there, and no clown is a guarentee to host a anenome. ive got 7 bta's 3 color varients, a yellow corkscrew as well, my 2 aussie blacks dont host anything but my trues host all the bta's but mainly the red's
