its super easy! and fun.
you just need a big enough tank (55 gallons +), room temperature water, sufficient filtration, and some natural decor providing plenty of cover. for food, get them trained on a high quality pellet diet early on and feed them that as a staple, but toss in any bugs or worms whenever you find them, feed other live food like minnows and aquatic insects every so often, and give them some kind of frozen treat once a week. thats all i do!
oh but i don't recommend bass unless you are very serious about it, because they require huge tanks (300 gal minimum), they eat A LOT (gets expensive) and they make a big mess, so top notch filtration is required. this isn't to say its impossible to keep a bass, just takes a lot more dedication.
