Answer 1

I guess a bass dreams about GOLD !

a big slow swimming school of Golden Shiners so it can feed easily lol

they sleep/rest in grass beds and near structure

Most all fish spend time in an energy-saving state that can be called"rest", and we might even call theirbehavior "sleep", though it is probably different than "sleep" in most land animals. Many fish, like Bass and perch, rest on or under logs at night. Coral reef fish active in the day, hide and rest in crevicesand cracks in the reef to avoid being eaten at night.
The resting behavior of fish is very different from their behavior the rest of the day. Many minnows, for example, which are very active in schools during the day, scatter and remain motionless in shallow water at night. Many fish "rest" or "sleep" during the day and are active at night instead, but almost all fish sleep.
There are some animals that never stop swimming, like many species o fshark, however, they HAVE to keep moving to push water through their mouthsin order to breathe, and they may still sleep while moving, we just don't know yet. Some sharks do rest for short times though

Then after a pair secong a number of them began waking up. additionally once you think of a fish is ineffective, if its nevertheless upright, faucet the glass or poke it gently with a internet because of the fact it ought to in elementary terms be drowsing.
