Houston’s Downtown Aquarium is preparing to welcome two rare adolescent Sumatran tigers, Kirana and Zara, as part of the Association of Zoos and Aquariums’ (AZA) Species Survival Plan. These sisters, born in October 2023 at the Nashville Zoo, represent one of the rarest tiger subspecies in the world. This particular species is estimated to have fewer than 400 in the wild.
Their temporary relocation to Houston is more than just a new home—it’s a crucial step in their development. The move supports their social and behavioral growth while contributing to the long-term goal of preserving their species through strategic breeding programs.
Aquarium’s Commitment to Wildlife Preservation

The Downtown Aquarium, operated by Landry’s Inc., currently houses Bengal tigers, Marina, and Apollo. These new arrivals come just months after the aquarium said goodbye to Reef, a 20-year-old white tiger who was humanely euthanized due to age-related health complications.
The aquarium has faced scrutiny from animal rights organizations over the treatment and living conditions. In response, it invested $4 million in 2019 to create an expansive outdoor habitat. It now offers naturalistic features, temperature-controlled areas, and space for enrichment. This investment reflects the facility’s ongoing commitment to animal welfare and conservation.
Aquarium staff emphasize that their animals receive world-class veterinary care and enrichment. The arrival of Kirana and Zara is seen as a chance not just to educate the public but also to raise global awareness about the critical state of Sumatran tigers in the wild.
Public Engagement and Educational Value
Though no official arrival date has been announced, the aquarium intends to open the exhibit to the public once the sisters have had time to acclimate. Aquarium officials say these young tigers will help bridge the gap between people and conservation. They are expected to offer visitors a close-up experience with an animal they might otherwise never see.
Through live talks, educational signage, and conservation-focused programming, the aquarium hopes to use Kirana and Zara’s presence. It will surely spark interest and inspire action for wildlife preservation, especially in Southeast Asia. Hopefully, it will solve illegal poaching and habitat loss that are rapidly shrinking tiger populations.
A Growing Role in Sumatran Tiger Conservation

Houston’s Downtown Aquarium isn’t just displaying animals—it’s becoming a participant in the global effort to save them. By caring for genetically important individuals like Kirana and Zara, the facility plays a small but meaningful role in the AZA’s broader Species Survival Plan, which is designed to maintain healthy, genetically diverse animal populations in human care.
As climate change, deforestation, and illegal trade continue to push species like the Sumatran tiger closer to extinction, these controlled breeding and awareness programs provide one of the few lifelines available. The hope is that efforts like these can someday help reestablish viable populations in the wild.
