For young ones, it's not worth the hassle. You're better off buying them close to home. The whole idea behind keeping w/c FL Os is to strive for the elusive 14 inchers.
Coral Reef park has a few, but the location I pm'd you "Glades Range" always has a few baby Oscars..Last Time I was there there was a pair with a good 40-50 2"ers.... I agree with Oddball though, the whole point is usually to obtain the BIG boys...their coloration is nothing special, regular dak brown to black with the normal stripe variations that change as they grow... I dont know about this weekend, but I know Ill be there next Sat...if I see any I could catch you ome and hold them on the side for you
