Teasing, no...more,playing its him. He is a cutie and we have our hands in all the time. Most likely he thought I was some mysis that I was giving the nem. He is always hungry, he could eat all day. Mine is good with inverts and I could,probably try him it's coral, but my lighting is not up to,par in that tank. I had some frags in their and he could have cared less. He is not a rock nipper like one we used to have. This one eats rations and swims...might have to upgrade those lights!
