My now single Gourami is an Opaline Gourami and a female and is the most easy going fish I have ever known. She lives peacefully with Angels and Corie's and for awhile was in with the Guppies who were breeding like it was going out of style yet she never ate any of the fry or anything. I guess each fish has it's own personality. I hope you get lucky with your Honey Gourami. I think I read somewhere they were more peaceful then the Blue or Gold Gourami?
As far as the Glowlights, who knows? Maybe they just got in a bad batch or maybe they were so stressed during shipment. I think is nothing short of a miracle that fish survive all that they do. Imagine being stuck in a bag and shipped somewhere. Not all Currier's are so careful either.
