New red terrors - sexing

[RealCrix220]

Hi
Got 3 new red terrors yesterday ( I think they look a bit pale because they was delivered to me and delivery was over 3 hours late so cold water and not much air but I saved them and they was basically white when they arrived )

I know it’s very hard to sex when they ate this young but I feel I have 1 male and 2 females

the photos below are of all 3, one of each I’d love to know what you all think as I’m trying to get a pair and try to breed them.

let me know your thoughts

They look like they are at that unsexable age/size. I was always under the impression that they needed to be a bit bigger in order to determine the gender.

I agree. A bit bigger and also more colored up would be helpful.
If I had to guess based on this though, I’d say first two are male, last is female.

I did think that but I thought there may have been someone who knew some traits

I’m reading a lot about speckles in the dorsal fin being a male trait but all 3 of mine have this it looks like

( gutted if I had 3 males )

This was aimed at first reply - Deadeye you got in there before me lol

One of the best tellers is that females have a black Mark on the front of the dorsal fin. And the striping, but that is older and only really when fired up.

One of them is a lot more slender then the others which makes me think it’s a female but who knows maybe that one just didn’t get feeding time haha

runt of the litter haha

The fish are not old enough to be sexed, you will need to grow them out.

Both male and female will have blue Spangling in the dorsal, anal and tail fin. As a female gets older the Spangling is much larger and disappears. A males is much smaller spotting and higher concentration

I’ve added 2 more today in the hope to get one pair which I could breed, the ones I got today were very beat up and under fed in the shop this is why I got them to be honest
I’ll put up some photos of the new pair and the original 3

the first photo is the new pair

2nd, 3rd and 4th photo is of original 3
