Hi!  One of my questions would be what temperature you find works the best. I currently have no heater in tank.   Nice to meet you by the way.

The pleasure is mine.  I keep mine in a greenhouse along with all my Aphanius and Cyprinodons, etc. so my water temps tends to vary during the day but generally runs around 75 to 85 degrees.  I have found that these type of fishes like sunlight and warm water.  In these conditions they lay tons of eggs.  I had a breeding group of around 10 and I could collect 100 eggs a day.  I have literally around 300 I'm raising now and have long ago quit collecting eggs.  My water here isn't super hard so I have started to add salt, calcium chloride, soda ash and sodium bicarbonate to my 990 gallons of water storage giving me water that is pH 8 and about 400 ppm calcium carbonate.  Granted these are descendents of fish I collected in 2006 from Tampa and I suspect the water there isn't that hard due to the amount of rain, although I really don't know the original water conditions.  I mainly did this because of the Cyprinodons and Aphanius.  I think they are a cool fish and really in the long run, an easy fish to keep and breed.  Good luck and let me know if there is anything else I can help with.

Bye the way, if you ever need more goodei let me know, I'd be happy to send you more free of charge to be sure you have success.
