Alligators typically grow between and per year after hatching, and are considered adults upon reaching a length of . It takes around 12 years on average for an alligator to become fully mature. As Muja was already fully grown in 1937, he may have been at least 10–12 years old when he arrived.
Conversely, a contemporary newspaper clipping reported him as being two years old at the time of his arrival. All documentation pertaining to his acquisition was lost during World War II. Such paucity of records is not uncommon and many zoos around the world find it difficult to determine the exact age of their older alligators.

However, it is not uncommon for alligators in captivity to live more than 70 years.
Health and lifestyle
Muja spends the summers in a pond and winters in a special chamber, which was renovated in 2016 to resemble a cave.
He is fed once a week and usually eats of meat.
His diet consists of skinned rats, rabbits, bird, horse meat and beef.
He eats this together with bones, which are good for his teeth and calcium levels.
Due to his old age, it is difficult for him to hunt for his food, and zookeepers instead place it right in front of his jaw.
Unless he is being prodded or fed, Muja is usually motionless, leading some visitors to inquire whether he is alive.
According to the zoo's veterinarian, Jožef Ezveđ, Muja has a good degree of mobility for an alligator his age.
In February 2012,
zookeepers noticed that Muja seemed to be experiencing discomfort in his right foreleg. A team led by veterinary surgeon Srećko Radojičić subsequently diagnosed Muja with

Prior to the amputation, Muja was given
local anesthesia

and tied down to the operating table. The procedure lasted three hours, and according to zookeeper Aleksandar Rakočević, was done using local anesthesia. Muja was given antibiotics before and after the procedure. "The very next day after the surgery he started eating," Rakočević said. "Every time he eats it is a sign of his recovery."
Afterwords, Muja was separated from a group of three young alligators that had arrived to the zoo from Cuba.
Muja's longevity has attracted the attention of social media users and the alligator has become popular on social media platforms such as
