Here are some pic;s of a Rostratus . I thought for sure this was a female and listed it on this sight as such . Long story short I Vented the fish using all the tools available to me that I had learned threw research Example : Flash light , Magnified glass exc.... It is to my belief this is a male and not a female Note I am not use to doing this . In my observation I see two holes exactly the same size and shape , One slightly more pinkish than the other Here are a few pic;s and a measurement of the fish just by looking at the fish comparing it to other Female it looks the part however I had read that a male may not show color in a mix male tank and that is what I have . What dose it look like to all the Rostratus keepers out there >
