The Tennessee Aquarium has reported its loss of two beluga sturgeons as a result of different health problems.

Communications Manager Thom Benson said in a blog that Boris died on Saturday, Horace on Sunday.

"When the aquarium's veterinarians performed a post-mortem examination, it appears both animals had been dealing with very different, but very serious health challenges," Benson said.

The two sturgeons had been moved last week to a new River Giants exhibit that is scheduled to open at the Tennessee Aquarium April 28.

Benson said they had undergone quarantine and a careful move that simply was a tipping point to the fish that had health issues.

In the post-mortem examination, Benson said it was found that Boris "was actually a female sturgeon and had been egg-bound with nearly 17 pounds of roe."

This situation, he said, appears to have "led to an infection which had taken over this fish's intestinal tract and was spreading."

Benson said that Horace's "right kidney had failed completely due to aging or chronic kidney disease."
