Last week on the Ohio regional trip to the Grand River I picked up 3 stonecats, 2 greenside darters, 2 blackside darters, 1 log perch, 6 redfin shiners, and one rainbow darter. Over the course of the week all but one of my redfin's systematically bit the dust, with brusing to their tail fin and eventually losing all control of their direction and depth. I figured they were just beating themselves up in a new environment but now one of my greensides have the same brusies along its caudal peduncle and fraying of the caudal fin rays. I am really starting to suspect that the stonecats are beating up on these fish-in-night. Has anyone ever seen this. I need one or more hiding places for the stonecats still but I would still like to keep one of them if I have to give the stonecats the boot. Any suggestions? Any thoughts or known occurances of this behaviour?
