Hi, I have a male dwarf gourami and two females in a 20 gallon long. The females are both conditioned, and the male built a bubble nest last night and this morning. The females seem to pick at the nest and the male chases them all around the tank, but it seems more territorial, and not like breeding behavior. The male is always a little aggressive towards the females, but when he builds a nest, he ramps up the anger. There are no eggs in or near the nest and he’s not really protecting it. He lets my tetras near the nest but when the other gouramis come up from the bottom he chases them. I’m wondering if there is anything I can do to make them actually mate, besides raising the temperature and feed well.(I’ve already done both for a week) I did notice at one point, both females biting at each others mouths almost like kissing gouramis. After one swam away, the male came over and flipped on its side next to the female that won the little sparing match. The female had no reaction to the male, so the male chased her around the tank until she hid again. Besides this, I have seen no breeding behavior, and the male is still tending to and adding to his nest. Any suggestions? Thanks.
