Most people agree that there aren't many things more entertaining than watching Clownfish frolicking in Sea Anemones, as in these Top Clownfish/Anemone Photos.

From the prolific Aiptasia to the colorful Hawaiian Maroon to the Blue Carpet to the Rose Bubble Tip, Anemones are terrific additions to most marine reef aquariums. Did you know that, without sea anemones, there probably wouldn't be any Clownfish in the oceans today? In the wild, Clownfish have little defense against predators other than the stinging tentacles of anemones. In an aquarium, anemones make colorful, cozy houses for Clownfish which seem to revel in being massaged by their stinging tentacles.

It used to be thought that all anemones required a very high water quality as well as fairly intense tank lighting in order to thrive. As more anemone research and experimentation has been done, it has been found that many anemones actually prefer lower lighting levels and seem to do quite well when their diet is supplemented with a few bits of the seafood found in your local grocery store's freezer case.

Not all Clownfish will take to diving into all Anemones. Before purchasing a Clown or Anemone, some research should be done to see which ones will most likely pair up. Host Anemone & Clownfish Matches will show you which match ups are most likely to succeed in your tank.
