Good morning I like your Tarantula. I have a A. sps. new river rust rump, it is 1 of the nastiest in my collection even though they ae supposed to be a docile species. It rears up + flicks hairs f you disturb her. I raised her from a sling + shes about 3 years old, half grown. I assume shes a female judging by how fat she is. It will a while before I know because they're a very slow growing species. Lanny
