hello new to this monster fish keeping but so excited. i have a 180 with 4 oscars, 4 parrots, two fresh water dragons, six catfish, two bali sharks and two africans beautiful colors. the other day one of my parrots that is totally yellow started to turn black from the top down. i originally thought that she was probably died from the store that i received her from to make her more appealing and i was willing to accept her in black, she would still be nice looking. then around three days later i have woken up to find suddenly the three or four day process of her turning mostly black had instantly reversed and she is all yellow again! what was it , how did this happen and other things came to mind and i figured i would ask the monster fish club for information because im sure someone out there has witnessed such a thing and mite have info for me. next i have to say that the temps ph and ammonia are all perfect, that has never been an issue because i check it sometimes two to three times a week due to the number of fish. next there wan no signs of distress at all from the fish? im simply curious of what went on and if it will happen again or a fluke. thanks
