I have a 10 gallon and was thinking of a crayfish, I have a bubbler and am getting a top fin internal 20 with spray bar. What's was wondering is if they need a small section of land or can they live underwater for there while lives and will they eat plants?

Crayfish can stay underwater their whole lives. They dont normally need a land area, but they will climb out of water to breathe if the oxygen level in the water drops too low. Except for the dwarf species (Cambarellus) most crayfish do eat plants. Some spp are worse than others.

I agree, a 10 gallon is a tad small for anything bigger then dwarf crayfishes

I've seen everywhere saying 5-10 for normal crays...it's the largest I am allowed at the time and can't get anything bigger.

Here is the tank setup for a single either rusty, red swamp or signal crayfish...don't mind the rocks as they are holding down the log to get it more waterlogged

looks good leave the rocks at the left side they look good and the more spots for the cray to hide the better.

I agree with keeping the rocks on the left side. Nice setup.

So I got a minnow trap and am going to set it up soon, it's a basic minnow trap. The river has a nice flow so where would I put it?

For crayfish you want slower water with rocks. Shallow edges of fast water are fine. I've never actually caught a fish in a minnow trap, so I will let others advise on that.
