Blue leg hermit not so blue

[Uhohhotdog]

I have some blue legged hermits and some of them seem to not have much color anymore. They’re a very pale blue.

Is this from a lack of some type of nutrition? They’re still very active but the color is just off.

I have some orange hermits and a red hermit in the same tank and their color looks normal.
