The associations listed are only true for the wild. In captivity, all bets are off. E.g.,
A. ocellaris may pair with
E. quadricolor. Fish don't read the same books we do.
The anemone looks like a
H. crispa. It's a little bleached right now, but in time, given good care, should darken up and be a rather spectacular specimen.

You don't often see the pink/purple crispa's too often.
