I caught this guy in a golf pond in Palm City, Florida (30 miles N. or West Palm) - rather my Son did. It can get pretty chilly there, vs. down in Miami. We catch them every year and they are spreading. I brought back a 4 incher that is in the quarantine tank. I have seen them schooling in full salt water. Schooling is a regular occurrence as you have to "find" them in the ponds, and the bait has to be at the right depth as well. I have found that live or dead mosquito fish are the best bait. The only thing that stopped their spread was when there was an infestation of snow king plecos that wiped out the entire pond - all plants eaten and then all fish disappeared like a desert. They apparently spread by the eggs sticking to birds legs. There was a cold snap and the plecos died - the ponds returned back to normal health (but w/ a higher percent of non-natives) w/in a couple of years. There are also black acaras (in the smaller ponds) and blue tilapia as well. BTW, myans make great snook bait.
