Nandopsis Haitiensis (Black Nasty) Progress Thread

  • We are currently upgrading MFK. thanks! -neo
And here is one that stays consistently white, but has no hump and tends to get chased around by the other more dominant black ones. Thanks for looking!

Would you all mind taking a look at this particular fish and giving me your thoughts on gender? This is all the same fish; but as you can see, it's colors can vary. Out of the six that are in the tank, this one has claimed the entire left half. It's the only one that looks like it has begun to grow a hump, but I'm still not sure...what do you guys think?

These all look female to me.

The one above looks male to me (so far), but is a bit too young to show a dominant male profile, although in my case females would also develop fairly steep profiles, so I never relied on profile alone as a sole gender judge. The female below had quite the macho head at about 10"-12". And without a male in the tank (I removed him) would lose a major part of her dark markings.

I'm not willing to guess from pictures I sex mine according to their behavior, all I can say is humps and color are not necessarily good for determining sex in this species male and females can be either color, and both can have humps. This topic has been discussed several times over the years with photos and videos showing the different colors on both sexes. Not sure why the same bad info keeps getting repeated. This is a excerpt from one of those conversations. (Hey Duanes, not to throw any confusion in there but just to clarify the dark dorsal thing. females dorsals will only get black in first 2/3's then white and tail fin will be white as well. males can have dark dorsals just like male festaes, and their tail can be dar or peppered also. for example look at my pair in this video, my male is jet black and the substrate didnt have a whole lot to do with it. Ive noticed by going with the refference of only females having dark dorsals,in the past i ended up putting two or three males together trying for a pair and obviously failed;) lol but after raising a large group and forming pairs was i able to recognize the differences. its a very small percentage of males that color up like mine but they are out there.)
