A few days ago I received my Gardneri eggs. The seller told me the incubation time was around 20 days but I read (from multiple sites) that it was closer to 14 days so put them in on the 20th instead of the 26th. They are in dechlorinated, 20 degree water with a small airline on a slow setting. I added microworms (very few) as I read that having these around makes the eggs feel as if thy are in a natural environment. No eggs have hatched as of yet, did I do it all wrong? What should I do next?
