i went to Clementi 328 shop and i saw a RTG look a like arowana.. so i ask the aunty how much was it and it's only $250, much cheaper then the other RTG! so i ask what arowana was it and she told me its a grade 1 mix RTG and a weird name for it that ends with gold. i would like to know .. what will the colour be when it's an adult and what is it called.. and why is it so cheap?
