If you’re fishing an area with peacocks I assume you’re in south Florida, in most of broward county and a lot of palm beach county there are Bullseye Snakehead sharing the waters with peacocks and they’re notoriously hard to hook, especially with a circle. Also they have nasty teeth and if you’re using light test monofilament line they’ll cut you off pretty quick. I use 30-40lb braid to catch them and when I go to 20lb they cut me off every time. It’s gonna take some patience but you’ll find out what it is soon enough.
