Freshwater · Year-round in South Florida canals; best in spring when pairs guard nests
Oscar
Astronotus ocellatus
The oscar is a big South American cichlid established in South Florida canals from aquarium releases — it is legal to keep there, but aquarium fish must never be released. Thick-bodied, boldly marked with orange-red marbling and an eyespot at the tail base, it fiercely guards its eggs and young and fights hard on light tackle.

Where they live
How to catch them
Baits around canal structure Lake
Rig: Light to medium spinning rod, size 2-4 hook with worms, insects or small shiners, fished around canal structure, culverts and vegetation
Bait/lure: Worms, insects, small shiners
Key tip: In spring, work baits near guarded nest sites — oscars strike intruders hard in defence of their young.
Tiny jigs and flies in canals and lakes Shore
Rig: Small jigs or flies cast tight to canal banks, fallen trees and vegetation edges in South Florida canals and lakes
Bait/lure: Tiny jigs and flies
Key tip: Keep presentations small and close to cover — oscars ambush from structure rather than chase in open water.
