Hatchet Fish and a Fiddler Crab

[freshwaterfishlover]

I have a 5 gallon, but want to replace it with a 10g. I Currently have a 10g with 2 Marble Hatchets and 3 Silver Hatchets. I love them so much I want to get more hatchets. I was wondering can a few Hatchets live with a Fiddler Crab?

im not 100% sure, but dont fiddler crabs need lots of land and a bit of water, and dont they need a bit of salt with them?

Yes Fiddler crabs need Salt. I forgot. I am just going to get a Fiddler Crab for the 5 Gallon.
