OK. time for an update. exactly 12 weeks and 5 days old. Both are female, one is slightly bigger and just over 6.5 inch.

I'm very happy with their development. Interacting extremely well with male P14. All the rays eat: Hikari pellets:- massivore, sturgeon, cichlid gold.
I will continue to update so we can all see their development

Pics taken today. The P14 is about 10 months old.
Thanks to T1K for these.
Quick video also.
