So I’ve had my baby blue tang 3 days now. I’ve noticed behavior I’ve never seen with other fish. When one of the other 4 fish in the tank swim by it the baby blue will follow them. Nothing aggressive just casually swims next to the other fish. Does this with both my clowns, melanurus wrasse and my two spot tang. Has anyone else noticed this? Is it potentially stress related because blue tangs like groups maybe? It is currently the smallest fish in the tank.
