Banjar could be best guess, lots some green color there. If not as green i'd think maybe could be like a panda gold hybrid. Panda arowana is mix between red tail golden aro crossed with xback gold but either way still nice inheritance.
+1 to both previous replies -- OP some additional pix with different or maybe a bit brighter lighting might help; if you're buddy still had a copy of the cert would be easiest.
