hi.two days ago my dad and i went to the fish store.finally,my dad bought me a chinese hi-fin shark.it's very small,only 7 cm long.i kept it in a tank that 1,2 m x 60 cm x 60 cm that already house 14 fish similar to its size.does my tank size is suficient enough to make him comfortable until he grow to 20-30 cm long?
