Like it says. I was getting ready to add my new ornate to my tank. And I was doing a good old "finger test" to see if the water temps were close. I know it's really scientific. And when I stuck my fingers into the tank my 8"+ jar freaking bit me. got me scratched good enough I started to bleed a little. this was my first time I have EVER got bit by any of my fish and I used to stick my hands in my RBP tank b/c people didn't think I would and they never got me.
Happened to me before too but I was hand feeding shrimp and mine was around 16". I didn't hand feed too often after that.
