Do fish just turnaround and say nope, not for me.
In: Planetary Science
I have a reef aquarium that has power jets inside simulating constant current, which is good for the corals.
I have at least one fish who will spend *all day* facing the current and swimming against itz staying in place. He sleeps in a calm spot surrounded by rocks.
Fish like to swim, are good at swimming, and are good at staying in one general spot.
