Goes to show how much i know eh...haha....so females don't get a dark spot in their dorsal?
I definitely didn't see it when I looked at him so I'm wondering if it's some kind of camera trick. LOL I can tell you though that Rusty Wessel once told me that you can't sex all Herichthys like that. In fact the only one he told me for sure you can that he could think of off hand was H. carpintis. I asked him about H. sp rio salto because I noticed in the breeding pair I had that the female had a black dorsal blotch and the male didn't and he said he couldn't say for sure if that was something he had noticed before.
