Janelle Posted August 13, 2007 Report Share Posted August 13, 2007 I have a tank which is not tropical with a mixture of coldwater and subtropical fish: goldfish, white cloud mountain minnows, pearl danios, peppered corys, and platies. It has a heater in it to keep it at about 20-22 degrees (this was installed after two borneo suckers found it too cold and died). So, with the heater keeping the temperature stable for me, and the temperature being above 20 degrees most of the time but not exactly *tropical*, does this still count as a coldwater tank? Just curious. =) Quote Link to comment Share on other sites More sharing options...
Caryl Posted August 13, 2007 Report Share Posted August 13, 2007 No, it is sub tropical. To me, coldwater is below at least 18C if not 16C Quote Link to comment Share on other sites More sharing options...
Janelle Posted August 13, 2007 Author Report Share Posted August 13, 2007 Ohhh, okay. Should I start posting in "Freshwater" about my tank then? =) Quote Link to comment Share on other sites More sharing options...
Caryl Posted August 13, 2007 Report Share Posted August 13, 2007 I don't think it really matters. You have goldfish and wcmm in there so keep posting under coldwater if you want. Quote Link to comment Share on other sites More sharing options...
wilson Posted August 14, 2007 Report Share Posted August 14, 2007 for me coldwater is unheated Quote Link to comment Share on other sites More sharing options...
carla Posted August 14, 2007 Report Share Posted August 14, 2007 I had this discussion in the LFS recently. They reckon the Corydoras paleatus are "cold water" fish and sell them together with the minnows and the gold fish as cold water fish = fish suitable for ponds. I thoroughly disagreed saying that only a few kilometers inland the people could well have ice on their ponds for a couple of days in winter and I do not think the cories would stand this. I feel we should really make a distinction here between an unheated tank in the house and a pond outside! How about you native people (as in "english as your first language" speaking people) come up with a suitable english expression for these two different cases and then we can all market our fish to the LFS's accordingly and educate them that indeed there is a difference between the two. Good idea - or not?? Quote Link to comment Share on other sites More sharing options...
HummingBird Posted August 14, 2007 Report Share Posted August 14, 2007 Yeah, like Caryl said, basically unheated in-house tanks are usually sub-tropical (though it depends on the house...) and outside is true cold water. Quote Link to comment Share on other sites More sharing options...
snookie Posted August 14, 2007 Report Share Posted August 14, 2007 what would paradise fish be (dont mean to hijack) :roll: Quote Link to comment Share on other sites More sharing options...
carla Posted August 14, 2007 Report Share Posted August 14, 2007 See snookie the problem is always where in NZ. In the middle of Whangarei you can keep a paradise probably in a bucket outside, as it won't freeze, but what happens in Poroti? Or in Rotorua or Taupo? Unless somebody tries it out we won't know. And to sell these things as coldwater = pond fish, I think is NOT the way to go. Quote Link to comment Share on other sites More sharing options...
wilson Posted August 14, 2007 Report Share Posted August 14, 2007 yea what can survive up north may not down here Quote Link to comment Share on other sites More sharing options...
HummingBird Posted August 14, 2007 Report Share Posted August 14, 2007 Paradise are definitely sub-tropical. The fact that they can survive at lower temperatures doesn't mean they'll thrive in them, in my experience they do best in the lower 20's (°C).

jn Posted August 15, 2007 Report Share Posted August 15, 2007 I'd think I'd refer to those 'inbetween fish' as 'cool-water' or subtropical fish. (or 'temperate'?). You can't really say heated or unheated cause as someone mentioned it entirely depends on where you are and how warm you keep your home. I'd say a cold water fish is one where just about no temperatue is too cold!! Anything else is not a coldwater fish As far as where to post, I'm really leaning toward subtropical too and I would post my own issues like this I think: - tank issues etc could go in freshwater (cause algae problems and water conditions etc. would be the same whether your tank is heated or not). - coldwater section for fish where people 'never' have to worry about the water getting 'too cold' (ie: goldfish, wcmm, leopardfish etc) - freshwater for stuff like the corys, BN's, Borneos, guppies etc that people usually keep in heated tanks (ie: fish that WILL suffer or die if the temp cools below a certain temp) Quote Link to comment Share on other sites More sharing options...
Caper Posted September 2, 2007 Report Share Posted September 2, 2007 oh my gosh...I feel so confused...tropical, subtropical, coldwater :roll: :roll: Okay...before summer came - transfered 3 goldfish from 10 gallon tank to 20 gallon tank - tank located in my livingroom (previously had thermostat set to 24) - began to lower the temp, only got to 22 when summer started (temp between 74 & 80 in summer) - tank still has 3 ottos in it Should I remove the heater???? Summer is all but over :evil: :evil: But hopefully still weeks and weeks to go before having to turn heat on in apartment. With the ottos and goldies, would I be ok to leave the heater in and say lower it to 68??? Caper :roll: Quote Link to comment Share on other sites More sharing options...
