Ideal predator fish?

[Palster]

I am more partial to Puffers and Trigger Fish for a predator tank (just my own personal preference). Some Triggers can be VERY aggressive though depending on the species. A fully grown Clown Trigger can reach 18 inches in length and at this size would be like having a buzz saw swimming around in your tank as they are not afraid to use their teeth. Puffers have tonnes of personality and have even been compared to "Aqua Dogs". My Puffer will allow me to pick him up and readily takes food from my hand but you have to be carefull that he doesn't bite when he gets fed as he is a good 10 inches long and growing.
