Need some advice

[Arekkisu]

This is Bluey, my cobalt blue. Theyre an unsexxed juve around 7cm diam.

They have never molted and theyve eaten 4 times since i got them in march (going by behaviour + abdomen size to know when feeding is needed)

Through the past couple of weeks ive seen them go whiter and whiter and now theyre almost fully white.

Is this normal? Does this mean anything?

First 2 images are from today, the others being about 2 weeks ago

Are you certain that's a Colbalt Blue?

If it is a male it'll be a light grey color. They young look the same until sexually mature. The females will be the blue.
