So I had a trio of blue Japanese lyretail guppies (2 females one male) that I decided to put into my 24 gallon cube with pea puffers. FYI, it wasn’t that bad an idea - similar water parameter prefs, similar food prefs, and they still get along.
Now the guppies have spawned three times over in just 5 months. Still... that’s not the problem. The problem is... all my fry appear to be females, including the first generation of fry that are now in their adolescence. I know all livebearers will have fry without developed sexual dimorphism and appear “female” until they mature. Well, the first generation is pretty close, and out of the 20+ fish, none of them appear to be males at all...
I chatted with someone over at April’s Aquarium who suggested water temperature might have something to do with it. I’ve only started the online research and only found one article on Google, and it was still not entirely clear. Anyone have any experience or insight with this?
