It's legal to keep as many as you want since they are not native. Once I get my tank running I am for sure catching some more. I love the colors especially the red and blue highlights. They make great Peacock bass and snook bait.
It's not really a freshie snook. I caught them in brackish water on a 2" mayans. At that same spot I seen a guy pull up a 2lb Mayan cichlid off a live jumbo shrimp. I just got back from a rainy day/boredom cichlid fishing excursion at my local canal. Heres some pics of the bigger ones I caught.
(I wear a size 12 just for comparison)
This is just a slab of a Mayan I caught last year just thought I'd post it to.
