i had one for about a year, cool and pretty fish ... we called him fragglerock cause when you look at him head on he has a big bulbous muppet looking nose. He, unfortunately had to go because he loved chasing and beating on my GATF's. I kept taking him out of the big tank, and putting him in solitary in my 40 gallon breeder, and try again, but he always went after them, and caused damage too ... the pike have a nice set of teeth on them. He grew faster than the ATF's, making the problem worse, and it killed me to get rid of him, but had to make a choice, and although he was doing fine, the 40 gallon breeder was way too small for a 9-10 inch pike. He was eating anything i put in the tank, pellets, krill dry and frozen, silversides, and feeders when he was younger. They are very fast, and if startled will leap out of the tank so be careful. It was kinda funny, he beat up my ATF's, but was scared to death of my little 3 inch golby at the time. Kinda like the elephant and the mouse. All in all, a very pretty fish, but i'd agree that other silvery fish that look like him could be a problem.
