I kept Monti Eaters for a while...Any shrimp is a goner in my tank, wouldn't last ten minutes and I've had bad luck with copper bands. Nudis always seem to do the trick and never have to worry about them eating other things.
On a different note... Anyone keep other nudis for fun?? They are one of my favorite things to see diving with all their different colors and sizes but i almost never see them in the hobby outside of lettuce/berghia
