I just put in blue and gold gouramies with my pearl danios, the guy I got them from said yes they could go together. No way! Took all the gouramis out, had enough of the battering, ended up with two dead pearl danios. I don't ask anyone for info anymore, go to the forum instead! Hope this helped.Think I will be able to keep a pearl gourami in a 35 gallon with some other gouramies (gold, blue, opaline)?
