I might be able to send you a bimaculoides within the next few months, but a bimaculatus is harder because, from what Ive read, they don't live in the intertidital zone (they live deeper). I find bimacs by looking under rocks at low tide, so according to what I've read I should only find Bimaculoides. They are almost identical looking, and can only be told apart (I'm told) by the blue rings in the eye spots. If the ring is solid, then you have a bimaculoides, if broken (chain-like) it is bimaculatus. Also Bimaculoides lays large eggs, while bimaculatus lays small eggs. My avatar picture shows the blue ring from a bimaculoides I caught, and kept, and I'm certain it was bimaculoides because it laid large eggs.
Are you sure you don't want a bimaculoides? Why the preference?
