Planning on getting my first jumping spider!

Soooo, as the caption already says I'm wanting to get a jumping spider. I've already got a Mexican red knee tarantula so I'd have no issues with keeping live food or anything like that. as far as I know because they're so small they wouldn't need much space. would a 28x15x15cm acrylic enclosure be enough? I could also get something else. I was just wondering if it would do well in an enclosure like that!

Also is there anything specific they need? I think they need pretty high humidity right? (I'm keeping snails so that shouldn't be an issue for me at all). But if there's anything else I'd need to know please just let me know! I want to do as much right as possible.

(I'm planning on getting a North Florida jumping spider sling btw, forgot to mention that before).

sorry that this post is a bit over the place xD
