Goofy clowns

[Delphinus]

In captivity, the answer is "it doesn't matter." Clownfish may take to non-natural partners.

My ocellaris hosted in BTA's for a few years when they were in the same tank. It did take some 6-7 weeks (or more; I don't remember anymore, this is going back some 6 years ago!) for them to go into them.

But to faithfully answer your question, in the wild, the following species are associated with Entacmaea quadricolor:

• 
  Amphriprion akindynos
  A. allardi
  A. bicinctus
  A. chrysopterus
  A. clarkii
  A. ephippium
  A. frenatus
  A. mccullochi
  A. melanopus
  A. omanensis
  A. rubrocinctus
  A. tricinctus
  Premnas biaculeatus

In a pinch, clarkii clowns pretty much host in all of the hosting anemone species.

Maroons and BTA's always make a nice display IMO.

It's too bad that most of the species associated with BTA's tend to be larger, more aggressive clowns. You have to really like clownfish!
