Hi guys my big male pearl gourami has spent the last few weeks building his bubble nest, i have stopped using an airstone and put a filter baffle to allow him to make it bigger. Hes had it up for a while now but still chases the female into the corner of the tank. Once in a while if he stops working on it the nest messes up, but he continues to build it back. My question is, how long before the female lays the eggs in the nest? Thanks guys.
