I want to breed my blue opaline gouramis. Shifting 1 male and 1 female to a planted 33gallon tank which is 36 inch in length and 18inch in height. The tank will be full of plants. I have ordered a couple. Should arrive soon. I was wondering what filter to use. I usually use power filters, but that would make too strong a current for the gourami to nest. So I was going to go with a sponge filter which is connected with an air pump, but I recently read somewhere that it creates a current strong enough to disturb the nest too. What are your thoughts?
