cyaneus quite rare. But from what ive read can be quite agressive, as in "clawing" and not letting go! gravid females to be "the worst"...but then again the heterometrus are quite "ballsy"
Also can have a pretty cool blue colouration.
xanthopus from what ive seen have different coloured legs to the body. So interesting to look at also!
Upto you! what do you fancy owning?
Can you not splash out and get them all? hehehe
