The size difference between my neon tetras

[Navfish]

I got some new tetras and compared to the one I already have, the size difference is crazy!

How long will it take for the tiny ones to grow if u guys know?

I can't really tell the size difference but when mine were smaller it took about 4-5 my months to mature.

Females are quite a bit larger than males when fully grown.

it should take about 3 months to get to full size if they are looked after properly.

Overhere it differs per individual specimen. Some grow faster than other from what I've noticed. I had some that were really XXL. About 4 cm (those were kept outdoors during summer) but their colors were faded. They look much nicer when smaller.
