I know if u want to bring out red in a fish you feed Keratin - prawns, krill, carrot, feeder goldfish etc.

If u want to bring out green then daphnia and green vegetables mixed into a homemade food.

I know pellets also can be good for enhancing colours.

Is there anything else i can feed to enhance my Blue Acara pair's blue or any other fish with blue colouration'?
 
keeping it varied has worked for me. Feed them a little bit of everything often and the colors will show. Good water quality seems to help as well.
 
My theory is great hard water quality is for blue coloration. I base this off of crayfish though. I use them as feeders for the most part and so their water conditions are usually horrid. They spend most of their time in the death holding tank with the other (feeders of the month). My son has the right to "save" one fish from the chaos and he chose a crayfish to go into my african cichlid tank.

The water conditions were the opposite of the soft acid waters the crayfish lived in. During the next two molts, the crayfish went from being redish-brown to blue! Unfortunately it didn't survive the next molt because the fish decided to taste test it when it shed.

Soon after, I dismantled the african tank and so I am not able to prove this theory other than the experience I had with that one cray. Who knows, maybe it was a blue cray all the time and the acidic waters just turned it red.

Is that possible, soft and acidic = red where as hard alkaline = blue? HMMM...
