According to John Tullock, here is a list of anemone's and the fish they host...
Entacmaea quadricolor (Bulb, Bubble Tip, Maroon or Rose Anemone) - will usually host Maroon, Bluestripe, Tomato and Clark's.
Macrodactyla doreensis (Long Tentacle Anemone) will usually host Clark's, Pink Skunk, Maroon, Bluestripe and Tomato.
Heteractis crispa (Leathery Anemone) will usually host Clark's, Bluestripe, True Perc, Pink Skunk and Saddleback.
Heractis aurora (Beaded Anemone, Aurora Anemone) only common aquarium clown hosted is Clark's.
Heteractis malu (Sebae Anemone, Singapore Sebae) only hosts Clark's in nature, may host Tomato and Bluestripe in aquariums.
Heteractis magnifica (Magnificent Anemone, Ritteri Anemone, Red Radianthus Anemone) hosts Clark's, bluestripe, Oscellaris, True Perc and Pink Skunk.
Stichodactyla gigantea (Giant Carpet Anemone) hosts Clark's Ocellaris and True Perc.
Stichodactyla haddoni (Haddon's Carpet, Saddle Carpet Anemone) hosts Saddleback and Clark's.
Stichodactyla mertensii (Merten's Carpet, Sri Lanka Carpet) hosts Clark's and Ocellaris.
(Natural Reef Aquariums, John H. Tullock, pg 208)
The first two types listed are the only ones recommended for beginner's in the hobby. The others are listed as expert care required. I was dissapointed to find out that the only anemone's recommended as hosts for ocellaris require expert care, as I have an ocellaris and am far from an expert.
BTW, my ocellaris (Nemo) and Regal Blue Tang (Dory) get along great! They both slide inside their own conch shell at night and sleep. Very cute. Can't wait to get them moved into the big tank and find an anemone for the clown.
Hope this list helps!
