Which month to bring to see aquarium

A random question, at which month did you bring your baby to aquarium? Be it sea aquarium or anywhere with big aquarium. And his eyesight has gotten better as he can see from distance (i assume from his consistent reaction) My 3 month old has started to like looking around his environment, people etc and wonder if at his age is it too early for him to look at fishes😂 #FTM
