I lost my last 4 Channa Micropeltes, literally the last 4 snakeheads in the state of Washington before the ban. We had them with 2 channel cats while finishing setting up a 300. One of them killed a channel, so we moved them to another tank which we FORGOT housed a 12" electric catfish at the time. Next morning all 4 snakeheads had broken backs and swam with a ridiculous wiggle as they couldn't control their tails.
Weeks sourcing the last 4 fish, paying way more than they were "worth" finally getting them and then a stupid mistake cripples all of them. I still feel stupid and guilty over that ordeal.
