I got my peacock cichlids about two weeks ago. I believe they are both female. One was a dark gray/ brown. She is now very pale gray, except for at feeding time, she gets darker again. She's showing no signs of stress, not being bullied and has plenty of hiding spots. My tank is STILL cycling. .25 ammonia .50 nitrite 20 nitrate Ph 7.2 First picture is the day I got her. Second is her today.
