Cory Colour Change

[Invicitus]

Hello, this might seem like a strange question, but I was wondering if lighter coloured juvenile emerald Cory (Brochis Splendens) change to a darker colour as they age?

Also depends on the substrate you have them on. I have 15 Green corys on pool filter sand and they all have a very light color to them.

Yes they will darken with age
