Vinnie Posted October 21, 2008 Report Share Posted October 21, 2008 I came across some freshwater crayfish the other day, can these be slowly brought up to live in a tropical tank or they only like cold water? and would they not bother the fish? Or if any one has any other info on them that would also be great Quote Link to comment Share on other sites More sharing options...
Romeo Posted October 21, 2008 Report Share Posted October 21, 2008 I've been told by a Koura farmer that the ideal growing temperature is 19°c. I've also heard from a guy on TradeMe who's had two Koura in his tank for a couple of years at 22°c+. So they seem pretty hardy, but the higher you raise the temperature the shorter their lifespan will be. Quote Link to comment Share on other sites More sharing options...
Stella Posted October 21, 2008 Report Share Posted October 21, 2008 Just because you can doesn't mean you should. It will be stressful for the crayfish and shorten its life, as Romeo said. There is a thread going at the moment on keeping them: http://www.fnzas.org.nz/fishroom/brand- ... b6a97fae3c Crays do make cool pets Quote Link to comment Share on other sites More sharing options...
Vinnie Posted October 22, 2008 Author Report Share Posted October 22, 2008 thanks for that guys. I'll be keeping them in there own tank now... but I'll try and catch some small fresh water fish from the river to put in the tank just to make it a bit more entertaining Quote Link to comment Share on other sites More sharing options...
Southerrrngirrl Posted October 22, 2008 Report Share Posted October 22, 2008 I'm pretty sure I read that as they crays get bigger they'll eat the small fish... From what I read, sounds like its best just to have one on its own. Thats what I'm gonna do. Quote Link to comment Share on other sites More sharing options...
new zealand discus man Posted October 22, 2008 Report Share Posted October 22, 2008 Hi Be aware that they come under fish farming laws..With MAF...Phill Quote Link to comment Share on other sites More sharing options...
Lynnie Posted October 22, 2008 Report Share Posted October 22, 2008 Gee they look interesting, Does any one want to sell me some? Got a spare tank. Quote Link to comment Share on other sites More sharing options...
Stella Posted October 22, 2008 Report Share Posted October 22, 2008 They do if you want to farm or sell them.... Not if you want to eat or keep them in an aquarium. There is no law against that. Indeed legally you can collect up to 50 per day for such purposes. Good luck finding that many at once though (some places yes, most places no). However you can't release them anywhere but where they came from (with a permit) and you can't take them from conservation land or certain lakes that are iwi-only for collecting purposed (Taupo, Rotorua etc) Quote Link to comment Share on other sites More sharing options...

Romeo Posted October 22, 2008 Report Share Posted October 22, 2008 Here's a bit of info on the legality of keeping koura from DOC. I spent 6 weeks hunting around Christchurch streams looking for Koura with no luck, so I had to buy some from Vince Scully, the Kaikoura Koura Farmer. I've had my Koura for a few months now and I'm loving every minute, worth the hype! Quote Link to comment Share on other sites More sharing options...
Lynnie Posted October 22, 2008 Report Share Posted October 22, 2008 No dont want to eat or farm them. I think they would be awesome to watch crawling around a tank. Your fish Stella are just great would like to see more of them. Quote Link to comment Share on other sites More sharing options...
Vinnie Posted October 22, 2008 Author Report Share Posted October 22, 2008 at the moment I have 4 in a 20 liter tank, 3 of them are 2cm long and the other 4cm so was thinking of fish (or tadpole) of round about the same size... if any problems start then i'll give the fish a new tank to live in. Still doing research on 'do frogs eat the crays or other way round, or not at all' but if any one knows any thing about that any info would be great Quote Link to comment Share on other sites More sharing options...
