I brought 4 of these cats for a breeding project and been told that I have 2 females and 2 males but I'm just after some other opinions.

Thanks

What I see is each and every time female

Males have "shells" on their chest which clearly overlap, while the female ones toch.

Further, males have curves spines in their brestfin. Again, clearly curved

Yes, but females have big fat bellies full with eggs. If these fish are females they must starving to death to be so slim. Try to feed them well some time and if they are females their bellies will grow.

They all look like females to me, simply going on the lack of a thick orange first pectoral fin ray.

I've been looking at the fins and 2 of the have longer and more curved pectoral fins, in fact the biggest of the 4 has the smallest fins.
They are looking a bit chunkier now, I don't think the lfs knows how much these gluttons can eat.
The lfs had about 20 of these but I couldn't spot any with any colour to the pectoral fins so I went for the ones with the larger fins instead. I didn't realise that all the pics didn't up load here is all 4 viewed from the top.
