Gannet Posted January 10, 2007 Report Share Posted January 10, 2007 whats the truth about them?? are they just the tropical ones? or are they a different species? Quote Link to comment Share on other sites More sharing options...
Alan Posted January 10, 2007 Report Share Posted January 10, 2007 There is no such thing Gannet. It is a ploy by unscrupulous LFS to sell a fish to unsupecting buyers. Yes they can be kept in unheated tanks. But not at Haast. Can a coldwater fish be kept outside anywhere in NZ any time? Yes, that's why they are called cold water fish. Guppies I don't think, would suvive a winter in Auck. outside. So the LFS to cover their butts on this one say, " Oh well, we just meant an unheated tank inside a house" Hope the house is heated thru the winter, because in most places thru winter, they wouldn't. They definately don't survive in my unheated fish room in the garage here. So the short answer is NO THERE IS NO SUCH THING AS C W G!!

Caryl Posted January 10, 2007 Report Share Posted January 10, 2007 Guppies are able to deal with lower temperatures than most tropical fishes, as are some barbs (like rosys, golden etc) and other fish. They are fine in "cold" water if the temperature is not less than 18C. The average well insulated house in many parts of NZ would not get below this, hence the term "coldwater" means "in a well insulated house in a warm part of the country so you do not require a heaterstat" 8) Quote Link to comment Share on other sites More sharing options...
Gannet Posted January 10, 2007 Author Report Share Posted January 10, 2007 thanks thats what i thought, thanks for conferming that. i ended up talkn to a person for an hour about this and thats what i said that there is no such thing, just guppies that can handel lower temps, but with no heating out side they will die. thanks for the comfermation.

Alan Posted January 10, 2007 Report Share Posted January 10, 2007 Caryl, as you mentioned them, I have had both the rosy and golden barbs survive in a bath thru the winter here. Shame we had the Awatapu flood here a few years back. They learnt how to swim in a REAL big pond then, never to be seen again. Quote Link to comment Share on other sites More sharing options...

Keri Anne Posted January 10, 2007 Report Share Posted January 10, 2007 Gambusia are often called "Cold water guppies" just as WCMM used to be known as "The poor man's Neon". However in the case of Gambusia they are a genus of the same family [Poeciliidae] as Guppies. They are considered a pest in NZ and have caused huge enviromental damage. From WIKIPEDIA: http://en.wikipedia.org/wiki/Gambusia As to why they are a pest? These may help: http://www.gambusia.net/ http://www.issg.org/database/species/ecology.asp?fr=1&si=126&sts= Quote Link to comment Share on other sites More sharing options...

Afrikan Posted January 11, 2007 Report Share Posted January 11, 2007 I keep Paradise Fish outside all year round, and it can get mighty cold even here in Hawkes Bay in winter, and haven't lost one, and boy do they get huge on that ongoing supply of live food that lands in their trough 8) Quote Link to comment Share on other sites More sharing options...
SpidersWeb Posted January 11, 2007 Report Share Posted January 11, 2007 Yeah Paradise fish are quite content in cold water. When I was a kid I always had them in cold. Put one out in my mothers pond once, netted it out a year later when they were re-doing the pond and it was absolutely huge. Danios will live for a long time in cold-water, but they lose their colour and look kinda washed out, only takes them 5 minutes in warm water to recolour though. And yeah coldwater guppies aren't 'real' as such but I hope you'd find that they were semi-engineered using darwinism, e.g. female guppy drops 30 babies in cold water, 2 survive, 1 of those becomes a female, the other a male, breed those two and we get 50+% guppies strong enough to withstand the cold, do it again... and so on. If that is not the case, then whoever labeled them as cold water guppies first deserves a poke in the eye. Quote Link to comment Share on other sites More sharing options...
Alan Posted January 11, 2007 Report Share Posted January 11, 2007 That in my opinion is not the case. They were lucky to survive. Try them next winter with a frost or two. Quote Link to comment Share on other sites More sharing options...
Afrikan Posted January 11, 2007 Report Share Posted January 11, 2007 We have rather a few frosts here, so much that I can't grow hibiscus or anything like that, because of them... :lol: Paradise been in such cold water that it hurts to put your hand in and they have been fine and dandy...

Ira Posted January 12, 2007 Report Share Posted January 12, 2007 You could probably breed colder resistant guppies given how fast guppies breed in a relatively short time. Say 300 generations if you start off with a huge pond of thousands and drop the temp a degree a year... Quote Link to comment Share on other sites More sharing options...
reef Posted January 14, 2007 Report Share Posted January 14, 2007 i have seen guppies at western springs in auckland. They survive all year round. are they not guppies. Quote Link to comment Share on other sites More sharing options...
