you are righ some of the colors are off a bit, but i will say this. cameras caputre colors we otherwise miss.
i've found c02 can make a difference in color as well. pictures taken with the same camera with c02 too low will appear bland and with c02 where it should be will be deeper colored to the camera
the rubin will actually turn a purplish color under the right conditions
the cleaning looks amazing.. the tank definitely did need it. i'd agree it looked liek some rhizo was getting ready to grow.. tank looks great hot shot!
the chromis looks beautiful as well. excellent pair!
