Question

do fishes sleep under water​

Answer 1

Answer:

yes they sleep inside the water at any time at day and night.

Answer 2

Answer:

Hey mate here your answer;

Fish do sleep with their eyes open, because they don't have eyelids (except for some sharks) to close! ... Most fish need to keep moving even when they're sleeping, so that they keep a constant flow of water moving past their gills to maintain a proper oxygen level in their bodies.

Hope it help...
