I would suggest to check if a lack of oxygen at the bottom of the tank might be the problem - especially reading about the swimming and resting behaviour. How is the respiration rate of the Corys? Do you switch off the CO2 supply at night? See: http://www.planetcatfish.com/shanesworld/shanesworld ...

Hello! Thanks for all replies. I chose to remove the eggs with an airtube, which was very easy.
