Tropical or cold-water ?
×
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

Which are hardier to survive or easier to keep ?
Is it true you still need a heater in a cold-water tank.

It varies from species to species. Some tropical fish are really hardy, some are not, and vice versa.
I've never heard of a heater being used in a cold water tank - maybe in the arctic, but our climate here is fine for them without a heater.

You wouldn't need a heater in your Coldwater tank if it is kept indoors as room temperature will be fine, can you define what you are referring to as 'Coldwater' fish?
If it's Goldfish these can be tricky in an indoor tank, especially in Summer, as the warmer water becomes the lower the oxygen level will fall and most coldwater fish need more oxygen than do tropicals. Another 'minus' - especially directed at Goldfish kept in tanks - they eat a lot and subsequently 'eject' a lot, so maintenance is much higher also.
You could keep 'temperate' fish, ie ones from lower temperature areas. A good example of this would be the White Cloud Mountain Minnow - also many of the African Killifish will survive very well at room temperature and, strangely enough, so will Platies. Guppies were also OK in the days when Guppies were hardy, but you might struggle with them nowadays.
All in all, for the easiest fishkeeping you really would be advised in my opinion to look toward the tropicals - you would have a much wider choice to select from, and they would be easier to maintain too.

Also, people mean different things by 'hardy'.
Some people take hardy to mean that the fish will survive no matter what. This isn't the case, if the water conditions are poor the fish will die, it might take longer to die, but it will.
I understand hardy to mean the fish will tolerate water condiiton fluctuations better than a more sensitive fish. So if the Ph, temperature, chemistry, etc. changes it has a better ability to deal with those changes. This doesn't mean that hardier fish don't require optimal water conditions - it just means if there is a sudden change they are less likely to go belly up.

Maybe cold water isn't the correct term. I saw some bubble eyed fish and Redcap Oranda which were amazing and was thinking of switching over as I have a tropical tank at the moment.
In the shop they said I should keep the redcap at about 22 degrees and still use the heater - thats why I was wondering if this was the norm in cold tanks.

Yes,
Some of the 'Fancy' Goldfish do need special attention as regards temperature, by hardy I was meaning hardy as in able to tolerate cooler - not poor water conditions .
They aren't the easiest of fish to maintain but very reqarding if you get things right (although they wouldn't be my 'cup of tea'.
