Do fish (bass/sunnies/pike) sleeps at night? If so, how long?

Question

My guppies sleeps at night by stop swimming and descent to the bottom. At night when i turn on my room light, they wake up and swims.

Answer 1

No the do not sleep. Sunnies and Northerns and perch sink near the bottom, and remain somewhat dormant. Bass may actually remain active at night and can easily be caught with floating rapalas reeled slowly across the water.



Take a bright flashlight and walk along the shore shining the light into the shallows, and you will be amazed at the things you can see.
