They are under 1 cm – very small. And no, I really dont think you can tell whether they are male or female, – I am not sure, but I think most fry look ‘malish’ when in this size. But with a camera like this it may be possible to actually try to document this along the way.
In this big tank I will not be able to see how they grow up but maybe in another tank.
