The Titan is probably the most aggressive trigger around. Grows to over 2 feet and is very aggressive, even at small sizes. It needs a very large tank and probably best if it’s the only fish in the tank. This is not a fish that you should play around with as it will not only kill all your fish but will attack your hand if you go into the tank.
