My bluegills in my pond had a couple leaches on thier fins and i had to pull them off because I'm not putting medicine in a 1,500 gallon pond. Well I put them back and I was reviving one in the current of the waterfall and my lmb is being pellet-trained and is being starved, and is VERY aggressive. He was inder the water hyacinth and a feel something clamp down on my fingers, he's only about 2 pounds and a foot long, but he made three scratches that drew blood and he actually cut my finger nails, he then tasted a way too big bluegill, had it halfway down his throat, and spit it out, it and has some gray scratches on it but is alive, and I thought he was going to be food...
