Weedy seadragons dance, cichlids shimmy, red-eared sliders flutter their claws and pufferfish draw patterns in the sea bottom to attract mates. Love isn’t just in the air—it’s underwater, so make a date to visit the Greater Cleveland Aquarium. With limited capacity for social distancing, the Aquarium has added “date night” hours and will offer a romance-themed “I Spy” challenge, animal enrichment activities, a Valentine’s Day photo op and a little mood music in the galleries. Advance tickets required.
