So I have had these rainbows for 3-4 months now and I just noticed some color differences in these fish. What I noticed is one has a blueish color to it. This is not a turqoise rainbow. They were bought from petco and were listed as Melanotaenia fluviatilis but I'm not convinced one of these is a fluviatilis. The yellow one looks more like a Melanotaenia australis. The one to the right of the first picture is the same fish as in the second picture. What do you guys think?
