Post number 4 my friend. It isn't theory. Do a search on here about damsels hosting things. They do. Clowns are damsels. Other damsels will host. Juveniles are the most likely. They are territorial and won't stay within anything for long, just long enough to feel safe.
I should have made it clear what I mean. Theory about how they can take sting. Its not fact. They THINK its the slime coat on skin etc.

Clownfish and damselfish are the only species of fish which can avoid the potent stings of an anemone. There are several theories for how this avoidance is accomplished. Firstly, the slime coating of the fish may be based on sugar rather than proteins so anemones fail to recognize the fish as food and do not fire their nematocysts, or sting organelles.
Secondly, the mucous coating may mimic the anemone's own coating, a theory that is bolstered by the fact that it takes several days for a clownfish to adapt to a new species of anemone. There is no adaptation period when a clownfish is moved to another anemone of the same species.
Thirdly, their unique movements, which are unlike any other fish, may let the anemone know that they are not food. This theory is bolstered by the fact that juvenile clownfish, which have no coating, will immediately seek refuge in any compatible anemone and will not be stung. Juvenile clownfish will not survive for long without the protection of an anemone, and few find one before being eaten.
