I've had mine for over a year....great eater-eats everything off a feeding stick. Just wondering if anyone has had one that got "aggressive". Mine has been pretty mellow for the most part....never seen it attack or bully anything in the tank. Not saying that stuff (goby/chromis/wrasse) hasn't "disappeared" in my tank....just think it's my lion/Rhinopias/Tessalata that's been doing the damage.
