Yeah, no. Definitely still alive with that thing on him. I'd honestly prefer them be innocent isopods so I don't have to trap everynight and worry all the time the next time I add a fish.Gotcha. It does look kind of like a cirolanid isopod but I'd need a closer picture to say for sure. I was just asking in case the brand new fish died from other causes and then the (possibly Innocent) isopods moved in to clean up the mess.
