Hello. I'm a reptile enthusiast who is very interested in adding a tarantula to my animal collection. Based on what i've seen and read the Costa Rican zebra sounds like a species i might want. I work at a pet store, and just this week we got in what the sellers SAID was a costa rican zebra/striped knee. However, upon comparing it to pictures of other costa rican's, i'm not quite sure if it is. Can they ever be brown? This one is a somewhat dark brown, with barely visibile stripes on it's knees. All the pictures i have seen are of more black tarantulas with much more visible stripes. Do they get brown before a molt? Or are these morons totally wrong about the species (and that wouldn't surprise me)? I have seen a picture of a costa rican zebra with a discarded brown molt before, so that is why i ask. Thanks for the help.
