https://www.reddit.com/r/Cichlid/comments/j99zf6/their_heads_turned_white_today_this_is_a_week/?utm_medium=android_app&utm_source=share i posted about it on reddit and got mixed feedback. Tank params are 0 ammonia, 0 nitrite, 10 nitrate, 7.8 ph, 76 degrees. I added what looks to be the opposite sex to what I have now and after a week their heads were white and then faded in and out. Any help is appreciated!
