Second largest pike cichlid ... a male will eventually outgrow a 125 gallon but it will take a few years. Awesome pikes though, my favorite of the big boys. Comes in three different colors. I think Snookin's are the Peruvian greens.
They aren't prone to HITH as much as some of their closest relatives in hard water, but it's always something to keep an eye out for. Nothing special other than making allowances for their eventual size.
