I have considered them many times, but no thanks.
Also, they are CITES class 2, meaning they are legal to import to Canada, but should be certified in their exporting country. No country currently allows exports, so any exported are by default smuggled. they are classified as globally threatened, locally abundant. Australia pushed for the CITES classification over Indonesian objection (where they are locally abundant, especially Irian Jaya). Then the Indonesians decided to not issue permits either, leading to smuggling. I saw many interesting regional variants of this turtle in South East Asia.
In any case, are you really ready to provide this creature the space it needs long term?
