Barnacle Posted December 5, 2012 Report Share Posted December 5, 2012 I have a couple of troughs outside for the animals, and just curious as to what species may survive. Currently the water is at 21degC, and expect it to get a little warmer the further we get into summer. A few weeks ago the water was completely green and opaque, so i threw some daphnia in there and its now crystal clear. So there is also plently of food for the odd fish. I have some platys, swords, guppys i can choose from. Also curious how a pair of killies may do any there... Anybody have any advice or opinions?

Caryl Posted December 5, 2012 Report Share Posted December 5, 2012 I have thrown tropical fish into an outside pond over summer months. Guppies, swords, platies, lots of barbs and tetras, danios and bristlenoses immediately come to mind. Quote Link to comment Share on other sites More sharing options...
JaSa Posted December 5, 2012 Report Share Posted December 5, 2012 Leopard Fish are perfect... Quote Link to comment Share on other sites More sharing options...
Ira Posted December 5, 2012 Report Share Posted December 5, 2012 I'd think all the fish you mentioned would be fine. Even a lot of cichlids would probably handle it once it's a little warmer if it doesn't drop too much. I've had my tropical tank down to 18° for a few weeks with no problems. They just swam a little slower. Quote Link to comment Share on other sites More sharing options...
supasi Posted December 5, 2012 Report Share Posted December 5, 2012 I have WCMM in a bath tub year round. Dont see them much during winter. The colouration of them cannot be matched in a tank. Must be something to do with the natural food and light. Quote Link to comment Share on other sites More sharing options...
Sophia Posted December 5, 2012 Report Share Posted December 5, 2012 killies do ok at that temp in summer but not sure how cold they can go in winter Quote Link to comment Share on other sites More sharing options...
hovmoller Posted December 5, 2012 Report Share Posted December 5, 2012 so i threw some daphnia I have thrown tropical fish What's with all the throwing :slfg: But seriously platys guppies swords would probably thrive in there and breed like mad if you THROW in some java moss for cover too Quote Link to comment Share on other sites More sharing options...
Caryl Posted December 5, 2012 Report Share Posted December 5, 2012 It's a little added excitement for the fish hovmoller at the start of their outdoor holiday Similar to a bungy jump without the extra bounce :thup: Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted December 5, 2012 Report Share Posted December 5, 2012 There are a lot of fish that would do ok over summer. I have had fundulapanchax killies and live bearers in ponds over summer and they have done well. Many barbs would be OK as well. Quote Link to comment Share on other sites More sharing options...
disgustipated Posted December 5, 2012 Report Share Posted December 5, 2012 i've had convict cichlids in huge buckets outside in the colder months and they were spawning regularly, it was a good food source for my oscars Quote Link to comment Share on other sites More sharing options...
Barnacle Posted December 6, 2012 Author Report Share Posted December 6, 2012 Sounds promising then. I'll give it a shot Quote Link to comment Share on other sites More sharing options...
F15hguy Posted December 7, 2012 Report Share Posted December 7, 2012 have heard of convicts, WCMM, leopardfish, guppies, swordies, platies, paradise fish and even Geo's (surinamensis type) and synspillums surviving Tauranga winters in outside ponds. my personal preference would be for paradise fish and leopard fish Quote Link to comment Share on other sites More sharing options...
David R Posted December 7, 2012 Report Share Posted December 7, 2012 Texas cichlids are one of the more northern species of cichlid we get here, could be worth atry. Gymnogeophagus balzanii also comes from a fair way south of the equator and certainly prefers cooler temps over winter. Quote Link to comment Share on other sites More sharing options...
89crwreck Posted December 7, 2012 Report Share Posted December 7, 2012 how would one acclimate a fish from 24 degrees to water around 18 degrees? Quote Link to comment Share on other sites More sharing options...
disgustipated Posted December 7, 2012 Report Share Posted December 7, 2012 slowly Quote Link to comment Share on other sites More sharing options...
89crwreck Posted December 7, 2012 Report Share Posted December 7, 2012 30 mins? hour? few hours? couple days? Quote Link to comment Share on other sites More sharing options...
Caryl Posted December 7, 2012 Report Share Posted December 7, 2012 My pond, when I set it up, tends to be warmer than my tropical tank and can sit around 28C. I would suggest no more than a degree per day, depending on the fish species as some are only semi tropical anyway so will adapt to the lower temps a lot faster.

F15hguy Posted December 7, 2012 Report Share Posted December 7, 2012 lol most species will handle temp changes of 4 degrees(or a lot more depending on species) happily, especially if its downwards, many use this as a sign of rainfall which triggers spawning behavior. I have measured the Ross river in Townsville which has temp changes of up to 12 degrees in a 2 hour period during the wet season. and the fish go into eating mode.... not dieing mode. acclimate them as per normally, just give them about 1/2 an hour to get temp ready... check using a thermometer to make sure, if temps are out by more than 2 degrees, wait a touch longer. acclimating them for too long will stress them more than if you just dumped them in.

Munkii Posted December 8, 2012 Report Share Posted December 8, 2012 Be careful. My outside trough changes from 21 deg during the day down to 16 deg over night. Quote Link to comment Share on other sites More sharing options...
disgustipated Posted December 8, 2012 Report Share Posted December 8, 2012 Be careful. My outside trough changes from 21 deg during the day down to 16 deg over night. i don't think a gradual five degrees is much more of a temperature fluctuation than most fish would ever experience in the wild. i really like the word fluctuation. regarding your original question, there really is only is one way to find out....

Godly3vil Posted December 8, 2012 Report Share Posted December 8, 2012 None of these fish have probably ever been in the wild though so their bodies would not know what it is like to have the temperature drops found in nature, that is what I would be worried about.
