Hi everyone, this is my first time posting so bear with me. I was reading other posts about people with similar issues but I am still unsure of what kind of Gourami I have. I picked up my Gourami for my lfs last week, they said they only had one male and were waiting on getting more. When I bought the male, they said that he should become more yellow in color once he’s comfortable in my tank. It’s been a week now, and the only color change I noticed was a black stripe on his side. Is this a young male that will lose its stripe and turn yellow? Or is it a female and my fish store doesn’t know how to sex their Gourami? I appreciate any help!
