When I do waterchanges lately my males cories try to get the females to spawn but they have nothing of it.
Is there anything I can do to help get the process going?
Do the waterchanges daily, sometimes it needs a prolonged effort, so keeping the males excited is the best thing to do. Having said that I am assuming the females/s are fat with roe.
I would say at least 5 gal and use cooler water to replace what you take out. as cold as it comes from the tap will be OK, as you are only changing about 15% the temperature change will not be that great.
