I just looked at my sig below... it doesn't mention that I have 3 green barbs. The gourami are one blue/opaline, one gold/3 spot, and one pearl all fairly large, mature and I believe male. The barbs are about 2 1/2 inches have had them all together for at least 2 years with the guppies and others and never had a problem, I guess sometimes you just get lucky with KIND fish, I hear others talk about agression between some of these fish - me, never. Only one that drives me nuts is the yoyo so now he lives in the 10 gal/planted fry tank (take that you big pest - now you are a baby sitter!!!).
