How fast does a male turn into female when his mate dies?
Situation: my female of my established pair is dying. She is at least 10 years old. The last few spawns she has become very prolapsed. Within the last few days she has become lethargic and stopped eating. Her vent area is bulged and I suspect there is nothing I can do, there must be some internal issue.
The male is still doing great. I have another fish I just sourced that is almost certainly female. She is in quarantine but that will take a couple more weeks minimum. she is slightly larger than my current male.
How should I approach pairing them up? I don’t want to wait too long and let my male start going female.

) and my attempted solution is to send the male through QT with the newly acquired female.
