Hi, I have a 20 gallon long stocked with glowlight tetras, corydoras, and a trio of blue dwarf gouramis. (One male two female) The male has made his first bubble nest and he’s only been in the tank for about 2 weeks. The females have been in for a few days and are in no shape to breed. The temp of the tank is 78 degrees, and my question is, since no females can breed with the male, will be still defend the nest and get aggressive with the rest of the fish in the tank? He attacks the females when they come into the corner of the tank that his nest is in, but he has done that since they were added. He hasn’t shown any signs of trying to court the females,(I think)but I don’t really know what that would look like because I’ve only ever bred corydoras, platies, and swordtails. Thanks for any responses.
