OK OMG I just saw my first snakehead.... my buddy has one that is about 2 feet long and is crazy.... this thing went after a feeder and slamed his face in the glass so hard I'm actually shocked it didn't break. I couldn't have kicked the tank that hard. Tell me about these fish, how big of a tank do they require??? how big do they get???? How hard are they to keep, like I see the power is it posible for this thing to break the tank???? be honest I know there crazy cool but does it get on your nerves sometimes when he is smashing the tank and making water go all over the place all the time??? I understand feeding but this guys fish doesn't calm down for a second. Please teach me??? his was a redline snakehead by the way. What is the overall difficulty of keeping these
