I interested in the same thing. My Naso does the same thing. Mine looks about the same size as the one you got and she rips the heck out of it. You can here the water rush at the top when she pulls on it lol. Also when I feed them, you always see the top of her head breaking the water at the top before I drop it in. Aggressive feeders.
