Well i would say both actually. They arent really a fish that is known for being agressive, but it is just one of those things your learn after owning an adult you know? He is a big digger, so i cant imagine having another digger like him. He also van be agressive, so i wouldnt feel comfortable having a smaller goby in the same niche, and especially not a little shrimp! Just my thoughts on the matter.
