Congratulations 🙂
I always say – if theres one, theres more ….
And its kind of normal too, to not discover the fry before they are actually rather big.
Also, – its kind of normal to say that, – if they have done it once, – they will do it again. So it is very good news.
I just found also, in my nagyi tank, that there are fry from at least two different batches,- some are rather big, – and some are really small still. This is usual, – the male, once he figures it out,- will continue breeding often.
I wish you good luck, – maybe if you can watch closely you can discover which one is the female 🙂 ..
