Im hoping my girl gets that big..she may be young still. she didnt gain much size last molt, but that doesn't mean much. 10.25 is a BIG spiderAt DLS, she was a full 10-10.25". She even bred successfully. I actually regret selling her. I raised her and the male since they were 3-4" DLS. I fed them pretty much at will, although I favored her. She was with me five years when I sold her. She was all the time sitting in a favorite open spot, except with her egg sac when she holed up. I wouldn't say that I power fed her, but did not deny her. Figured she was a large fast-growing tropical that warranted frequent feeding. Hissers and big dubias were her mainstay. Her disposition I would say was defensive. I'd've not dared try to handle her ever.
I guess I'm going on here because she was so different from my brachys and gramms that love to keep and was such a neat different kind of T.
