For the 3rd or 4th time (I lost count), your 20 gallon is already maxed out. You shouldn't be adding any more fish.

How big of a tank do you need to house crayfish anyhow?

 

a 10g is a good size

 

Iight, thanx.

 

Usaly 10 Gallons is sufficent for an ordinary crayfish and as long as you have fast fish they don't tend to be agressive or do any damage, but as the others said it might not do well since your tank is pretty full.

EDIT: Their coldwater, so they won't do well in a heated tropical tank.
