[Killietalk] Diapteron, australe, etc.

I just wanted to stimulate some discussion on killietalk about my hatching techniques that seem to be working for all species of non-annual killifish, especially useful for Diapteron cyanostictum and Aphyosemion australe.    This is essentially the basic steps. I collect the eggs about every third day by picking from the mops and placing in room temperature tap water that has been freshly drawn from the tap and contains chlorine/chloramine about 1-2 ppm. I store them in 12 oz deli cups about one inch deep for 2-4 days and then pour off most of the water and replace it with dechlorinated (by carbon filtration) tap water. I use no other fungicide. In another week or more the eggs hatch and are transferred to a one gallon shoe box with some micro worms (Walter) and a portion of Java Moss and automatic water replacement. By this method I get better hatches and eliminate the destruction of fertile eggs by egg eating wormâlike critters. Of course, infertile eggs still fungus but the fungus does not spread to fertile eggs. It has been suggested that I try this with annual eggs by rinsing the freshly collected eggs in tap water, but I suspect it may take longer to kill the little worms. I plan on running some experiments where I store the collected peat in tap water for a few days before drying and storing in the incubator. I will try it first on Simpsonichthys marginatus where I am getting eggs that disappear during storage in peat.
