Hubby keeps saying he wants a crawfish or crab for our 36g corner bowfront. From what I've been able to find, crabs need to be able to get out of the water, so they won't do, which leaves crawfish.

I can't seem to find much on keeping a crawfish, what kinds of fish they go with, and what kind would be good for our tank. Currently, it is home to 12 serpae tetras and 5 zebra danios, a big hunk of mopani wood and several fake plants.
 
All of your fish are fast swimmers, which is good if you plan on keeping crays. Dwarf crayfish (C. Shufeldtii) will not eat fish and stay small, but you might want to get something more common, like a cobalt blue crayfish, which is usually for sale at most places and doesn't grow past 5", usually 3.5-4. Although the cobalts can be expensive.
 
I keep Dwarf Crayfish. 1.5" max. 2" I've never seen. They breed pretty easily, but I haven't found a way to stop killing them just as fast when I do wanter changes. Even with as small as they are, I would make crayfish a species only tank.
 
C. shufeldtii gets to 1.5", other dwarf crays could be bigger though. They're fun little guys with personality.
 
crab do not have to leave the water to survice. They will climb in the filter out of the water sometimes and that is more then enough. I have fidler crabs and crawfish in my tank. My fish are large enough that they do not bother them. Give plenty of rocks to hide under and they are fine.
 
Dwarf Crayfish are small, but they will most certainly eat anything they can catch. It's not much, but they will. They don't eat plants. They do dig.

Fiddler crabs most certainly need a way to access air, not land specifically.
 
Looks like I'm the only one who has dwarf crays that don't attack anything? They'll walk right past my BBGs and otos.

And to the last two posters, fiddler crabs should be given land, and not just "access to air". That's simply cruel.
