Ong Ming Siang, 33, received one of the largest fines ever meted out for such offences for keeping the animals in his apartment in a housing estate.
Siang pleaded guilty to contravening the Endangered Species (Import & Export) Act and the Wild Animals and Birds Act today, The Straits Times reported.
The 32 endangered animals included three rare ball pythons, two Indian star tortoises, a slow loris, three black-tailed prairie dogs, two sailfin dragons and five ornate horned frogs.
The animals seized were not indigenous and had been brought to Singapore without permits, according to the report.

Further investigations revealed that some of the animals were given to Ong while others were bought by him.
But AVA's prosecuting officer, Yap Teck Chuan, said there was no evidence linking Ong to any wildlife smuggling syndicate but asked for a heavy fine as there was evidence to show that the animals were for sale.
Singapore is a signatory to the Convention on International Trade in Endangered Species of Wild Fauna and Flora.
The AVA said permit was required for any import, export or re-export animal.
