Augustjd27 Posted January 2, 2021 Share Posted January 2, 2021 Hello, I am thinking of breeding some guppies in a 15 gallon aquarium with my German blue rams. The aquarium is heated to 84 F at the moment. Would guppies be able to breed and thrive at such a high temperature, or would it need to be lower. Interested in anyone's opinion on the ideal temperature to breed guppies for maximum production and fish health....a range would be nice to know also if possible. Thanks guys!

Daniel Posted January 2, 2021 Share Posted January 2, 2021 Based on another thread from yesterday it would appear that somewhere in the 84°F - 86°F is near the top end for livebearer reproduction. I know I had Endlers at that temperature and they bred like...well...guppies. Definitely faster than the discus they shared a tank with could eat them. 1 Link to comment Share on other sites More sharing options...

lefty o Posted January 2, 2021 Share Posted January 2, 2021 ideal temp for guppy breeding imo is 74-76 degr. they will breed in quite a bit warmer, and quite a bit colder, but the temp also affects their metabolism thus warmer shortens their life, cooler lengthens. 1 Link to comment Share on other sites More sharing options...

For maximum production I would be more concerned with the available hiding spaces and the rams' appetite than the temperature. 1 Link to comment Share on other sites More sharing options...
Fish Folk Posted January 3, 2021 Share Posted January 3, 2021 Agreed with Fonske — the main concern I’d have is keeping fry alive with Rams. We’ve raised lots of both, guppies and rams, but never together. As for guppy temps, they can go high, but not constantly. Our mini pond outside on the back porch would rocket up to 90-degrees in summer heat, but would settle back down too overnight. We had tons of guppies born in there - but it wasn’t like a home tank where heat was constantly on. Might be time to buy a new tank! 😅 1 Link to comment Share on other sites More sharing options...

Augustjd27 Posted January 3, 2021 Author Share Posted January 3, 2021 Additional question to everyone... which would be a more ideal temperature for guppies, 60F or 84F? Link to comment Share on other sites More sharing options...
lefty o Posted January 3, 2021 Share Posted January 3, 2021 neither would be more ideal. however, if you want them to be active instead of sluggish, go warm. Link to comment Share on other sites More sharing options...
