Didn’t get a reply, to my 1st post fish that have the trident / center point that protrudes out the middle I see them on Congo tetras, and clown killi fish… is this a male only trait??? I’ve got a small shoal of Brichardi tetras, and all but the smallest, had trident tails, did I get a bachelor group, or can females of some species get the trident tail??
I'm not sure about congos and clown killies, but on my emperor and rainbow tetras both males and females have an extended central caudal ray, although the male one is significantly larger and more noticeable.
In my never identifiable Phenecogrammus type, both had extended middle rays, but males' were much longer. I knew I had both sexes because I had one fry, but it only lived a couple of weeks.
The difference in the caudal extension was very evident.
