Need help on breeding blue gouramis

I would recommend getting a sponge filter. Although depending on how long it takes your gourami to get into action it may not matter - it would worry me to death.

Make sure the female has plenty of places to hide, as the male will chase her all over if she bothers him before he's done building his nest.

You will probably want to remove the female as soon as they're done, so the male won't beat her up. Be careful not to disturb the nest though - that could be tricky. Perhaps have a divider handy, so you can simply seperate them without having to chase the girl around.

I can't tell you much else, as my gouramis have only made attempts in the community tank and I don't have room right now to set up a special tank for them. They're quite interesting to watch, I actually witnessed the release of eggs and it was an amazing dance. Unfortunately for me, the eggs attracted the other fish, who'd otherwise been leaving that corner alone and the nest was destroyed.

per your other topic, http://www.aquariacentral.com/forums/showthread.php?t=91004 please review it.

For what it worth, if you not willing to listen to other people when they have experience with this matter then I dont know what tell you. Gourami have literally thousand young, same size as betta young, they need specialize food, specilize care, if you not willing to invest in their need then there's no point on wasting the effort to breed them. there topic around here somewhere on betta breeding Journal. I would suggest you read it and then consider if you want trouble of all that mess.
