funny question for a fish site. just for clarity you are talking about the Goliath versus a baboon spider, the Goliath is the most massive but is a bit smaller than the baboon. the giant huntsmen being the largest spider. and more than like the fastest and meanest of the 3.
baboon are diggers, so need a deep sub-straight to borrow in. Goliath not so much but do need a place to den. Both are nocturnal.
both show same aggression, if they do not feel threatened they will not bite, and allot of the time when they do they do not inject venom.
The huntsman another matter, and not something I would keep.
