Brad Wallace January 9, 2015 Fish fitted with prosthetic eye at Vancouver Aquarium Brad Wallace January 9, 2015 This is neat. Doing surgery on a fish is a weird concept but its obviously doable. Cool. Hope the fish does well. In the first surgery of its kind at the aquarium, head veterinarian Dr. Martin Haulena replaced the real damaged eye with a fake one, so that other fishes in its tank would stop picking on it for looking weak and sick.
