Here’s pics of a shrimp nibbling my nails. If my fingers are anywhere near them they put out their feelers and then jump on nibbling away. They seem to like nail care most of all . It feels tingly, their little grabbers are quite strong, you don’t want to be reincarnated as algae and meet one of these guys. Even the 3 sae have a go at times, anyone else have nibblers, must have algae growing on my hands.
