I will clarify. H. Malu is supposed to be cream or yellow (sometimes with patches of a dark yellow or orange). Depending on where it has come from, I believe (but might have gotten this backwards) Hawaiian Malu are more likely to be white/cream.
This is true, but to my knowledge they are the only species which (as adults) host in H. Malu. That's why I said most, not all, clown fish don't like it. Almost all juveniles will use it though, not matter what their species.
