On the other hand, african black knifes are much tougher, and even more readily available. One would fit your stocking list much better.
I see... my acara is generally shy, she rarely leaves her cave and shares it with the plecs at times... maybe I wont go with glass knives, and ill try for an ABK instead. the ABK would be cheaper anywho, and wouldnt take up as much room.
