It us Very hard to tell them apart and you will be making a guess
Females have a more curved dorsal fin and are heavier set then males, also females tend to be dull in comparison to males.

Sexing: Hard to determine, but the female may have a grayer stomach whereas the males are solid black.

Mine has been confirmed female. I have attached a pic. You'll notice her dorsal fin is curved, and her head and belly are lighter than the rest of her. It's not really easy to see the color difference. It took me a long time staring at her to figure it out, so I enhanced the color a bit.

Interesting question.

I was lead to believe that the Females are more rounded in the abdomen as Prodigy suggested. As to colour, I did not know there was a distinction.

This contradicts what Sova posted.

I would also like to know.

My red tailed is very black on whole body, and has rounded abdomen.

Maybe some other member can sort this out.

Cheers

The female Pics in this post are mine... The male one is i found in the Google.

The photo colour are different,... and the directions are also not the same. So, their colour should be diffenret in here.

Some of my red tail have rounded abdomen, their head are more large than male and have light colour.


Where are the Expert.... lol

Nexie, that's not a read tail shark, it's a "rainbow" shark. They are very similar to red tails, except as you know they have the red fins as well years ago they were known as red fin sharks for this reason, but they are a different species to the red tail As for the gender, I have no idea I'm afraid, but going by the back fin I would say male (but this could be movement in the picture) although the top fin looks more female so wouldn't be 100% lol

Hi Guest,

Could you please refrain from commenting on older posts that have already been answered. This pushes new and potentially very important questions down the list.

Your right, I think that post with the pics was backwards-
My rainbow shark has a lighter colored belly and a distinctive black stripe across its eyes like zoro lol
A black spot on its tail,
And a black trim on its back lower fin, other then that dark grey/ black sides and bright healthy red find which seem to be more pointed (like most male fish) rather then curved like most females

that is a rainbow shark different from the red tail shark. The red tail only is red tail. While the rainbow is all red... Drosal and whatnot
