hi just set up my first tank 120 L got 3 zebra danios and 2 are really bright blue strips and 1 is very faint , they all play together and eat together and seem very happy ( they never stop playing , wish i had that much energy ) most of the time its the faint blue one that chases the other 2 so i dont think he is stressed , so why is he not so blue ( he is nearly white )
thanks
thanks
