RE: New Webpage: Incubating/Hatching Aphy. australe eggs

["Genade Tyrone <tgenade at sun_ac.za>" <tgenade at sun_ac.za>]

At 26oC I was getting fry growing up with the parents so the eggs were incubating. I think that 28 to 29oC is far too high. I would take a look at http://www.killies.com and follow the incubation ideas for the australe. You may want to put an airstone in the incubation tub in future.

Keep well
