Robert Keeney Posted October 27, 2022 Share Posted October 27, 2022 I have some Xiphophorus variatus in outdoor containers. Recently we had an unexpected low temperature for several nights. The water temperature was as low 44 degrees. The fish are fine. This got me wondering about what the lowest temperature these fish can survive in. Do you have any first hand experience with this you would care to share? Link to comment Share on other sites More sharing options...
The Arthritic Aquarist Posted October 27, 2022 Share Posted October 27, 2022 I've had some in the past but never kept them any lower than in the 60s. I would tend to think that 40s is a bit cold for them, especially long term. Link to comment Share on other sites More sharing options...

I’d say 50-55 degrees is the absolute benchmark on a permanent basis, and even then it’s not exactly optimal. Link to comment Share on other sites More sharing options...
Robert Keeney Posted October 27, 2022 Author Share Posted October 27, 2022 While I appreciate your interest, I am looking for someone with real-world experience with keeping this fish outdoors. I have found nine collection sites in western Montana.

nabokovfan87 Posted October 27, 2022 Share Posted October 27, 2022 Might not be relevant, but...... This is always a fun vlog when I think about outdoor tubs. Link to comment Share on other sites More sharing options...

If you call a guy who painstakingly puts his out in May and brings them in in October (I’m in the alps, so winters are quite harsh) a reliable source then yes. Have a nice evening!

Have a nice evening! Our weather is not harsh unless you count hurricanes. It rarely freezes here. Yes I think you will do for a reliable source. It's not really relevant to my question, I did enjoy watching it. Link to comment Share on other sites More sharing options...
