Well I do plan on breeding her at some point in the future (I want to produce an Axanthic Spider for myself) and I will get a rack system for that. I haven't decided if I will keep her in a tank or move her to the rack when breeding time comes. But I have time to work out those details.
The funny part is that we got her as not much older than a hatchling and that was the only tank that we had, so we put her in it and she did fine. The only issue we have ever had was she once escaped (but we found her the same day).
