Anyone know the compatibility of 2 larger sized knifes. I have a 18" Royal and who is a little on the aggressive side and would love to add another to my tank. Good idea or no??
I would not try it. I have tried it twice with only 8-9" one's and never had luck. The established one always shreaded the new add to the point that I had to remove it.
That said, I do know of some folks that have been able to do it.
