Retirement and forum shutdown (17 Jan 2022)

Hi,

John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.

I wish to thank John for his hard work in keeping the forum going.

With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.

I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.

If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.

I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.

I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.

Thank you
Darragh Sherwin

Do fish sleep?

Hey guys,

Came into my room after being out, turned the light on in my betta tank to check something and he was sitting/resting on the bottom of the tank?


After a second he just bolted up and started swimming, was he asleep? :crazy:

Niall,
This is a complex question, I don't think they actually sleep in the sense we could understand.

What we need to understand is that out in the wilds (apart from in really densely-covered rain forests) it never gets completely dark - whereas in our houses when both room and tank lights are turned off and curtains are closed it does (get totally dark).
With no light of any kind fish get disoriented and I suppose they would just settle to the tank bottom under those circumstances.
After all, anglers night-fish for many species - but there again, it never gets totally dark out there.

This is an interesting topic and one which deserves further discussion, can anyone add to - or refute - my theory?

John

Of course they do... just ask the Mafia! They often send people to sleep with them :woohoo:

In all my fishkeeping years I have never seen my fish close their eyes.... it hard to sleep with your eyes open but then again I'm no fish, nor do they answer my call, so can't give an acurate answer... although I'm sure there's some dr doolittle out there who think they can :lol:

My girlfriend says i sleep with my eyes open :ohmy: so i guess that fish do the same and they sleep when we are in bed and wake up when it gets bright outside early in the morning

Something fishie going on here

I wouldnt say they sleep rather just rest on the bottom instead?? i've seen a documentary on the rift lakes and in it they say the fish go into a sleep like state at night?? most of the fish i've kept have done the same with the exception of some catfish and a black ghost knife fish.

Sleep is one of the most interesting but probably most misunderstood physiological subjects (in any animal).

If they do, it probably is not like ours.
I would say that it would also depend on the species. (this is purely guesswork by the way).
A fish that lives in caves may be better poised to have a sleep than one stuck in a shoal of a hundred in mid-water.

Having the ability to "wake" rapidly upon stimulation is not really a signal that fish do not sleep.....they may be just tuned to react whilst asleep (if they sleep).

We do see with a number of species a bit of drowsiness for a short time after the lights go on.....is that a sign of sleep?

Do fish only need a very brief period of sleep?
We know that the average sleep of a dog is about 3 to 4 times longer than that of a horse (well..at least in captivity), and that does not affect the horse (often it looks as if Horses never sleep.....for anyone who walks around the countryside drunk out of their head at 3 in the morning ;)).

Possibly the definition of sleep needs to be looked at.

Is there not a team in some lab somewhere measuring the brainwaves of neon tetras.

My fish definitely have chill out time but don't know if you can call it sleep.

Are they the ones they changed the colour of by messing with their genes?
