OK, they’re not fish to eat, but only to look at.
The Shedd Aquarium is open for free on Mondays and Tuesdays all this month, as well the whole of next week, Feb. 15 through 19.
The free admission applies only to the original galleries, and not special exhibits or the Oceanarium, but there are plenty of fascinating fish to see, even if you only look at the Caribbean Reef, Shedd’s 90,000-gallon circular habitat in the grand rotunda. Built more than 70 years ago, the giant tank is home to more than 70 species, including butterflyfishes, stingrays, sharks, pufferfish, tarpon, lobsters, parrotfish, lookdowns, royal grammas and a moray eel.
Historic fixtures in the rotunda range from terra cotta tiles depicting crabs, lobsters and fishes to bronze skates and nautilus-shaped lamps made of capiz to the grand aquatic clock.
