Blood parrot fish

[Patrick_Fish]

I got 2 new blood parrot fish one yellow and one green with black dots. The one with black dots has turned yellow and the yellow one has started to turn black but still has some yellow. Is this normal? I have had these for about 4 weeks now!

Those are most likely dyed which is a very cruel practice(I'd google this if your not familiar with the process) the color will start to fade over time. With regards to the black spots are generally caused by stress, but in some cases they are normal color morphs over time.
