Sand Crabs @ the Beach

[BlueWater]

I'm an avid surfer. Usually later in the afternoons or
during a tide change, I can feel the sand crabs beneath my feet
borrowing into the sand. They're not crabs that are sold in stores.
Kinda' look like Scarabs.

Are these things safe for a reef tank? Harmful to anything?

I dont know for sure...but I would be concerned with introducing contaminants into the tank.

Bad idea, they are referred to here in the gulf states as Mole Crabs, and that's exactly what they do is act like moles, they'll burrow through your sand (prob under your LR, causing more problems).
But they'll destroy any type of sand bed you have going. To further, they are intertidal creatures, meaning they are adapted to that high-energy/ high oxygen zone, that you don't have in your tank.

So I wouldn't do it, If I were you, but that's just my HO.

coolness. Wasnt gonna' do it. Just curious.
The water here isn't quite something I would want to put in my
tank hehe. Like taking a rat from the sewer and putting it in my
hamster cage without washing it

Just wondering why it's not in the trade.

Thnx

They'd probably make good trigger/eel food. something like that
