Apistogramma Trifasciata ID help

[Chad]

Hey all
I tried to post this in the ID section but it seems I can't, not sure if that's cos it's my first post or cos the section is new, so I'll post here.

Today I bought 2 apistogramma trifasciata and I have a couple of questions. Both of my apisto's are a fairly bright yellow colour and they are about 2cm long. From the reaserch I have done on the net it seems they are both female but I was just wondering at what size and age/size does the blue start to show on the males?

One is also slightly larger and it seems to be being a bit aggressive towards the other would it help to get 1 or 2 more?

Any advise is appreciated and whn they have settled I can also try to get sum photos.

Pictures will go a long way to getting you a usable answer instead of a good guess!

And I moved the post for you.

Here are the pics sry for the poor quality i think i need more practise. They are both of the large fish as the smaller one is camera shy.

For my money that’s a female trifasciata.
The fry and juveniles I have are showing signs of being males at around 20mm.
