Hey, I've been signed up here since 2009, which was the first time I decided I wanted a little 8 legged friend and after 2 years of researching on and off and thinking it over I think I'm going for it. Been ringing round a few places looking for the right species at the right price. I think my number 1 choice is Mercatoris, being as they don't get too big and can live in smaller tanks, availability seems dodgy though so I'm happy for any dwarf species I think, obviously apart from blue ring. Has anyone got any tips for actually purchasing one? Like how do I know that the octopus they have is what they say it is? Is there a pictoral ID guide anywhere? Or should I take it on trust? What should I be looking for health wise when I see it? Thank you!
