I have had this guy for about a year in my office. I originally got him out of a feeder vat at my lfs to cycle the tank but quickly fell in love with him:whistle:. recently he has lost 75% of his black color and turned a really shiny brassy gold color. I still think he looks good but I'm worried something is causing this color change. Water is pretty good, nitrates get a little high sometimes between water changes 50%/week-10 days. but everything else checks out. He is in a 30g tank with an Atman 800lph canister and a sponge filter with a 600lph powerhead. gets indirect sunlight about 11 hours a day sometimes i turn the tank lights on in the evening when i'm there or have meetings etc...
So what could be causing this color change? is it something natural for them to change?
