You will find he will change colour almost daily, my Rusty had a fair amount of orange/red markings when I bought him at 1 1/2", by 3" he was completely black, now at 5" he has orange speckles.
i have found a website of someone with gold oscarfish could he be one?
i asked nan where she got him she said pets at home.... so i cant imagine he would be? gold oscarfish
I would suspect he is going to be a tiger to be honest, wild ones are usually more expensive as I would presume the gold would be as they are less common.
