Female/Male Agassizii?

[TT088]

Apologies as I note this is a frequently asked question and difficult with this domestic colour morph, is anyone able to help me sex this agassizii fire gold.

I have a definite male in a separate tank, however I am unsure on the fish in question (pictures below). Cannot tell if it is a female or juvenile male.

For reference it is around 4 - 4.5cm. Currently being kept in a separate tank to my male, just with some small tetras where it has now been for a few months, I was hoping that I would be able to ID it by now but still struggling. Unsure about age, however I purchased the fish in December 2023 from LFS and it has grown slightly however the male I purchased earlier in 2023 grew very quickly in comparison (not sure if this is relevant/helpful).

I appreciate that this may be a case of waiting and watching development, but if anyone is able to shed any light it would be great, thanks. (Photos attached).

From the shape of the fish, its age and size, I would expect it to be a female. But you know the problem with color-enhanced domestic strains.

Hi Mike, thanks for your view on this a few of weeks ago. I just added the fish in with my male a couple of days ago and found it in a cave today with a batch of eggs, so it was in fact female.

Thought that I would give an update as it may help others with a similar issue with these domestic colour morphs.
