NORWALK - The Maritime Aquarium in Norwalk is open for business this Presidents Day after completing what they call a "FINtastic RefurbFISHment."
Aquarium officials say new exhibits and upgrades cost $4 million.
The aquarium was closed for renovations late last year.
It unveiled 21 new exhibits and more than 300 new animals on Saturday.
This is the biggest change to the Maritime Aquarium in a decade.
