Mine love anyone that brings them food
The sorority especially will swarm to the side of the tank you are on, probably hoping you are bringing more food. Even if it's food related love, they do interact in a much more direct way. The tetras will drift up to the top at feeding time, zip around eating, and wander off. The bettas swarm and wiggle and dance and slide over and under each other trying to get to the next pellet. Same action. One kind just puts on a better show!
