Hi guys i was wondering how long do cynotilapia afra jalo reef take, to get a nice blue color, i have 8 of them not sure if they are females or males, but they havent changed their colour, they are 2" maybe a lit less, they are all brownish with most of them top yellow fins, but none of them turning blue. How long do they take to turn to blue i know only males will, not females. I have them in 125g tank with 6 aceis. I FED them with NLS THERA A, and HIKARI GOLD. Once a day every night, give them quite a lot and smash the pellets for them to be able to eat them. Once a week i give them squash. And thats it. Weekly 20% waterchanges with prime and stability.
