Fish with a funny float gets a CT scan at the Denver Zoo

DENVER (AP) — A fancy-looking French angelfish that was found one day with a funny float has its buoyancy back after taking some time out of its tropical trappings to get a CT scan at the Denver Zoo.

A zoo worker recently noticed the blue and yellow fish was swimming with a tilt, prompting a visit last week to the facility’s on-site hospital for an ultrasound and the CT scan.

The CT scan took place in a machine large enough to fit a 700-pound grizzly bear, so some special accommodations were required, zoo spokesperson Jake Kubie said. The seven-inch fish was sedated, balanced upright on a sponge and had water poured over its gills to keep it alive as the scan took place.

The diagnosis: Too much gas. Enteritis, or inflamed intestines, had resulted in increased internal gas that was affecting the fish’s buoyancy, Kubie said.

“It was treated with antibiotics,” he said. “It’s dong much better and swimming normally.”
