I have a heavily planted 20 long and started with 8 pygmy corys. Now I think I have about 15 and today I noticed them doing the chasing and mating thing again. My tank was comfortably stocked in the beginning now its heavily stocked and pretty soon I have a feeling that I'm going to be overrun with pygmy corys. Anybody have any ideas on how to get them to stop? There is a gaggle of chili rasboras, a couple hillstream loaches, about five cherry shrimp, and a single honey gourami. I was thinking of rehoming the chili's and some of the more amorous Cory's them putting in something that will actively eat the Cory eggs. Anybody have any ideas on a fish that will play nice and eat eggs?
