I was reading Magnum's recent thread here https://www.fishforums.net/threads/restarting-my-sunrise-wake-up-lights.496684/ and it got me wondering. All my tanks with lights that turn on and off each day do so using a basic timer. So there in nothing gradual happening. My mind started to wander which sent me to Google Scholar where I asked just what the title of this thread asks.
I got back some intersting studies which made me refine my search and wound me up on the paper. It is limited in terms of viewing to either have an institutional access or else pay out of pocket to see it. But the Abstract is available and maybe you will find some of it as interesting as I did. I have italicized that part below. If you are not familiar with Latin names for fish, the ones in this paper are zebra danio.

There are a number of studies involving sleep in all types of fish. Apparently Blind Cave fish have an unusual slapp pattern. A read mention of that but did not read on what exactly that meant. i think it was that they sleep a lot less than most fish.
I have know for years that Platys have been used as a major tool in the study of melanomas. I knew zebra danios also had a major role in a lot of science but not about the sleep stuff above. This is why I love spending hours now and then surfing Google Scholar on fish related topics. I just get curious and I cannot help myself.

Abstract
Sleep is a globally observable fact, or period of reversible distracted rest, that can be distinguished from arousal by various behavioral criteria. Although the function of sleep is an evolutionarily conserved behavior, its mechanism is not yet clear. The zebrafish (Danio rerio) has become a valuable model for neurobehavioral studies such as studying learning, memory, anxiety, and depression. It is characterized by a sleep-like state and circadian rhythm, making it comparable to mammals. Zebrafish are a good model for behavioral studies because they share genetic similarities with humans. A number of neurotransmitters are involved in sleep and wakefulness. There is a binding between melatonin and the hypocretin system present in zebrafish. The full understanding of sleep and wakefulness physiology in zebrafish is still unclear among researchers. Therefore, to make a clear understanding of the sleep/wake cycle in zebrafish, this article covers the mechanism involved behind it, and the role of the neuromodulator system followed by the mechanism of the HPA axis.https://pubmed.ncbi.nlm.nih.gov/38150068/
