A white tiger from Landry’s Downtown Aquarium in Houston has been put down, a spokesperson from the aquarium confirmed to KPRC 2. Reef, a 20-year-old male tiger who lived in captivity at the aquarium’s tiger exhibit, was a beloved animal in the community. In a statement confirming his passing, the aquarium said that the difficult decision to euthanize the animal was made after his “quality of life began to decline in his advanced age.”
