What no one tells you about fiddler crabs

[Sea Monkey]

I like my pair of fiddler crabs a lot. But what I never expected was that they poop. A lot! Here is a picture of my tank after less than 24 hours after cleaning the poop off the bottom. Holy crap! Can I say crap on this forum?

Oh boy. I would not like that. I would be adding something to darken up that substrate, I think, so it doesn't show up so much. Rocks maybe?
