woke up this morning and my 11" lima was floating around the tank. Had a bad bite mark on his tail area. I'm not sure what nailed him because I never see it. I have a 25" royal clown knife, 24" black aro, 13" florida gar and a 14" fire eel. This lima always stayed at the top of the tank so I'm thinking it was the aro, if the gar would have nailed him he would have been cut in two I think. He was always chasing the aro and I think he might of grown tired of it. BUT since I introduced the fire eel a week ago the knife seems to be aggitated. Not sure if I should try a tig or if it would be to riskey.. I need a faster growing tougher fish
