G'day
This guy started off as my dominant male bass, he has been over thrown by two much larger bass now. He went a very sooty dirty colour, while the other tow boys stayed the classic clean yellow with ink blotches. This fish has looked absolutely rubbish for the last 6 months. Over the last two weeks his gill plate has gone completely black when excited, and I think now looks quite good. Phone pic is rubbish but the pattern is now very complex.
One of the rare occasions when a cichlid being suppressed over a long period of time has actually made the fish look good (different).
Half way through the process of setting up two 6x2x2.5's. May chuck him in one and see what happens to his colour, whether this new black colour intensifies or he returns to a normal look.
