Can't help much with husbandry, but you might be interested to know that Mobile Basin spotteds have been elevated to a full species, now known as Alabama Bass (Micropterus henshalli). The nearest native Spotted Bass (M. punctulatus) to you are in the Tennessee River or maybe one of the coastal drainages in Mississippi. Both species have been introduced to the Chattahoochee.
Be sure to follow the letter of the law when it comes to taking game fish home. Wildlife agencies may or may not care what you do with "bait" but they'll throw the book at you if you break the rules with bass.
I'd love to see these guys (henshalli and punctulatus) available in the hobby, so if you can get some and breed them, that'd be fantastic!
