Poor quality pic makes it impossible to even guess...
Since Trimacs are rare and Trimac hybrids are common, unless it come sfrom a reliable source as a Trimac, I would suspect it's a hybrid.
I wouldn't breed it and distribute the offspring unless you could confirm it's "purity" (via a reliable supplier)...
But as a 'pet' call it whatever you want. They both have the same needs and come with the same expectations, so it doesn't really matter does it?
