Not every anemone is a suitable host for every clownfish. In the wild, certain anemone species play host only to very specific clownfish species native to their common region. Other anemones don’t play host at all, often packing a very powerful sting instead. When picking out an anemone for your clownfish, keep in mind that what you’re selecting may not be naturally occurring, and just because you put a clown and anemone together, they may not be accepting of each other. Some clownfish will refuse to reside in an anemone and choose instead to take up residence in corals. Anemones may sting and kill the clownfish. To make sure things work out, pick anemones and clownfish that are found together in nature and you’ll likely not have any issues.
