She was malnourished and had a few lacerations on her neck. The aquarium says Eloise quickly charmed the staff with her antics and easily progressed through her rehabilitation goals. Eloise’s rehab has been focused on nutrition and transitioning her from gruel to learning how to eat fish on her own.
