Can you give a discription of it? Coloration, mouth, finnage? The pike that comes to mind first is Crenicichla vittata...which it most likely is...second is Crenicichla jegui....but there are many other pikes that could go by that name as well. Common names are hard to go by but for a few of the pikes as they vary from region to region. Thats why we try to stay as scientific as possible when we discus pikes.
