Hi, I'm not sure what this guy is. It looks like a very hairy caterpillar. He has wrapped himself up in a blade or several blades of grass and appeared to be eating the algae off my tank...it didn't notice him until the grass stopped floating at the edge of the tank and started climbing down the wall. In the tank I only have amano shrimp, feeder minnows and some black mollies....at first I thought it might be a larvae from the shrimp, but after looking up photos I'm not so sure. Any help appreciated. thanks.
