Ember Tetra Colour

[90FScaper]

I have just purchased a small batch of Ember Tetras from my lfs. They are a much brighter orange than my first batch bought from a different store! Does anyone know why this might be the case?
Thanks

I have a little shoal.of eight and I do notice their colour goes up and down depending on what I feed them. In particular Tetra Min seems to bring the colour up.

Maybe just different strains with different amounts of red pigmentation, or maybe the ones at the fish shop were fed with colour enhancing food to boost the red/orange?

I can’t get Embers to colour up in my tank.. I’ve had them from different sources but they all remained pale, despite being in a densely planted aquarium and fed good quality foods.🙁
