I would be willing to bet that it was a honey gourami in breeding colors. There have been studies that show how inaccurate our memories are in recall. This is one of the reasons that even with an eye witness in a crime, many innocent people go to jail. From the Innocence Project:
"Eyewitness misidentification is the single greatest cause of wrongful convictions nationwide, playing a role in nearly 75% of convictions overturned through DNA testing.
While eyewitness testimony can be persuasive evidence before a judge or jury, 30 years of strong social science research has proven that eyewitness identification is often unreliable. Research shows that the human mind is not like a tape recorder; we neither record events exactly as we see them, nor recall them like a tape that has been rewound. Instead, witness memory is like any other evidence at a crime scene; it must be preserved carefully and retrieved methodically, or it can be contaminated."
Just a little bit of info for your Friday! I think this kind of thing happens to all of us. We reverse colors, remember two things and combine them into one, etc.
