When a fish dies ...
×
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

... sometimes it floats, sometimes it sinks to the bottom.
Is this an indication of the cause of its death?
Just wondering !

Google says..... initially they normally sink unless their swim bladder is filled with air, soon after death the gases caused from the bacteria digesting their flesh not being able to escape causes them to float, if left they then explode if left long enough!
so if thats true it must be the time between when they pass away ( rest in peace!! ) and when we see then that must be taken into account!
i think!!!!!!!!!!!!!

Ive read before that it can help determine,however I dont think this is 100% true. Certainly some fish will have their air bladders full when they die and hence they float. Others will sink and after gaseous build up in their decaying body they will release in the tissues and make the fish rise to the surface. Once surfaced,the gas again gets released over time and eventually sinks back down, whereupon it will again go through the process and may float another time before it finally rests on the bottom. Firstly you probably will have spotted it before its gets around the floating the second time! Also the size and density of the fish will determine how quick it floats as well as the water temperature.
Unfortunately its the same with humans, which is why there is a golden search period when someone goes missing at sea,the bodies can expect to float twice within a certain period. I think 10 days is the first time and somewhere towards the 20 day mark also.

Valerie,
when a fish dies, it will float or sink depending on the life it led. If the fish was a good fish and tried to be betta it will go to heaven, ie it will float.
If the fish was bad, led a life of crime and murder, it will sink and go to hell;)
