try to introduce the gourmai to your 200g but watch carefully this second you see one start to get touchy feely with the gourami using their mouth take the kisser out!
i tried it... while i was putting the gourami in, the oscars rushed over and were practically sticking their mouths up from the water... so i decided not to. Anyone interested in a kissing gourami that lives in southern california?
Here's a much more in depth profile for this fish, not just stats. The guy who wrote it recommends keeping them in like 4 ft. tank, which, is like a 55 to 75 gallon.
