We've been working at getting a group of 8x Bronze Corys (Corydoras aeneus) to spawn for a little while now. We tried a sand-bottom, species-only set up. Nothing. We added a powerhead. Nothing. We did cold water changes. Nothing. We fed a lot of different food. Nothing. We added rain water, catapa leaves, alder cones, oak leaves, and a bunch of small crypt: finally got some action! Not sure if the eggs are fertile, but they were laid everywhere. See annotated photos below:

Looks like a bunch are infertile. We'll see if anything happens by the top of next week or so. We'd love, love, love to raise a batch of wee corys!
