I’m not sure what prompted Kam to ask this question. Perhaps it’s because we saw fish in the pond at the park, (see our post do fish have ears?). Nevertheless it’s a question asked – several times now.
Fish and Brain Patterns
Fish do rest, but whether they sleep depends upon how you define sleep.
When people sleep there are specific changes which occur to brain wave patterns and ar processed in the brain’s neocortex area. Fishes don’t have advanced neocortical development, they don’t display the associated brain-wave sleep patterns.

“Yes they do. Muchli has stripes, Bambooram has stripes. They are female and male tigers.”,
“Yes, they do mum.” Pause,
“Why do zebras have stripes?”
