Adding crabs to a cycling tank?

[Brett W]

My tank is in its 12th day of the cycle, ammonia is starting to decline a little now. I was at the aqua shop and spoke to the owner (Marine Biologist) which told me I could put some crabs in the aquarium as long as the phosphate level was u 5. What are your thoughts on this? My phosphate is at 2.

I'd wait.
If ammonia is dropping, then nitrites. Then nitrates. 0's across the board.

First start the nitrogen cycle before adding anything.

Thats what I was thinking too,not sure why he told me that. My substrate and rock were are all dry products to avoid unwanted critters in my tank.This may take a while to get bacteria established. Yet another reason i was leaning toward waiting till it has completely cycled.

I wouldn't be to concerned about 'critters.' They will reach your tank one way or another. It's apart of reefing, it's how you respond that will determine if your a lifer. Good luck.
