Bettas and Corridoris

Question
I recently purchased a male crowntail Betta and have him in a 2 gallon filtered tank with a heater.  Can I add a corridoris to this tank, or will the betta be intolerant of another fish in the tank?
Thanks!

Answer
You should add at least two Cory cats to the tank with the betta. He will most likely leave them alone and if he does not leave them alone he will after he bites them once.  They are armor plated and have very rough skin.   I keep my bettas with a small shoal of tetras.... dave
