Schuyler Posted February 9 Share Posted February 9 In nature, annual Killifish last their eggs in dirt so that when the pool dries up the eggs will be protected until there is water again. In the hobby most people recreate that by giving them a jar full of coconut fiber or peat moss. The thing is that when you pull the jar out it's almost impossible to know how many eggs are in there and digging through the dirt to find the eggs is tedious. Looking for alternatives, I found a few people on Facebook that swore their killis would use a spawning mop in a jar. My pair were just frustrated and offended when I tried that. But looking more I found that in a lab setting they use a very fine sand (carab sea moonlight) for dirt and then they use a mesh colander and gently sift the eggs out of the sand so that they can count them and pack them in coconut fiber to incubate. They say that this can damage some eggs. But it has me an idea: use large grain aqua soil as dirt then use a sieve with holes big enough for the eggs to fall through. Luckily my dad lives close by and will take any excuse to justify owning a 3D printer so he made me two sizes of sieve. Then I plan to use some extra UN Controsoil and a thoroughly washed and rinsed salsa jar. 3 Link to comment Share on other sites More sharing options...
