Baby Urchin... But it's White?

[dangles]

I recently discovered a baby sea urchin in my tank. It's a relatively new tank, and I have 2 urchins there already, but given the short duration the tank has been up, and that I've only seen this one, I doubt my 2 urchins spawned. I did just get an order of TBS live sand, which I suspect is the source.

But he's white. In the photos of baby urchins I've found, they're all already brown. He's about the size of a pee. See below...

These are the best photos I can get so far. He's been cruising around "leveling up" his "armor" every day

Any thoughts?

Albino maybe? Not unheard of.

When pink pincushions aren't super healthy they can turn white, and those are super common in tbs live rock/sand. They're totally reef safe but eat a lot and can get baseball-almost softball sized. Mine has grown from a golf ball to a baseball size in about a year

Let's see if they have seen them before!

I got a pink one as a baby too from TBS at like an eraser size and in 2 months he's ping ball size. they grow up so fast ;-)

I got this guy a few months ago from my LFS. White with pink tips.

Tiny pincushions are adorable; juveniles we see are cream, light grey or faint pink.

As it Pigs out on all that Coraline, it will get some color.
