Talk about a fish out of water!

A French angelfish at theDenver Zoogot a CT scan this week — and the zoo gave animal lovers a peek into what that process looked like.

On Tuesday, the Denver Zoo shared two images of the fish getting the X-ray scanon Instagram. The zoo wrote alongside the surprising snapshots that it provides the “highest level of care” to all its residents and that specialists decided the angelfish required a CT after the fish was observed swimming abnormally.

“Have you ever seen a fish get a CT scan? 🐠 Here at Denver Zoo, our animal health and care teams are dedicated to ensuring every single one of our animals receives the care they need to thrive,” the zoo noted in the social media post.

“When animal care specialists in Tropical Discovery noticed a French angelfish was experiencing buoyancy issues and swimming abnormally, they brought the fish to our new Helen and Arthur E. Johnson Animal Hospital for an exam,” the post continued.

Medicine teams “sedated” the fish — shown in one Instagram photo resting atop a sponge — and “ran water intermittently over its gills” while it was examined and given a CT scan.

“We’re happy to share that this little fish was on a treatment plan and is now back to happily swimming in its Tropical Discovery home,” the Denver Zoo added about how the angelfish’s buoyancy issues were resolved.

Curious animal lovers can go on a tour of the Helen and Arthur E. Johnson Animal Hospital, which gives visitors a 45-minute “behind-the-scenes experience with an expert guide,“according to the zoo’s site.

In July, 11-year-old Charlie Clinton of Oklahomacaught a Pacu in a neighborhood pond. The fish, which closely resembles a piranha and is native to South America, has teeth that look like those of a human.

The Oklahoma Department of Wildlife Conservationwrote on Twitter(now known as X) at the time that while Pacu fish “are generally harmless to humans,” dumping unwanted animals in waterways is “so harmful to native wildlife.”

“DO NOT RELEASE YOUR PETS. THEY ARE AN EXOTIC, INVASIVE SPECIES THAT CAN CAUSE DAMAGE TO OUR LOCAL ECOSYSTEMS,” the department tweeted with a photo of the Pacu caught in Oklahoma.
