Colour enhanced Hormones African cichlids

[crunch7]

Recently I purchased few African cichlids for my 60 gallon community tank. I have found out that they have been subject to colour enhancement hormones. I would like to know if the fish will be able to recover to natural colour if at all it becomes dull and whether the hormone food have caused any long term problems in the fish. I brought 2 blue peacocks 1 yellow peacock 1 red peacock and 1 dragon blood cichlids.

Also could you suggest how to make some good quality fish food in veg at home. I wanted to buy nls spectrum but it's really expensive. Has anyone used hilarious sinking cichlids Excel ?

Thanks in advance.
