I have noticed in my new tank the fish are all cool mostly the tangs during the day, the occasional chase around the tank and show of fins but in general they swimming together. What I noticed is as the lights are in sun set mode and the tank is going into evening the aggression levels raise a lot, ESP the tangs chase each other around protecting their holes that they sleep in.
Then sun rise and the entire day they swimming around eating nori together and grazing.
Is it pretty normal?
