I am looking for definitive (if there is such a thing) answers on the following:
Are there any specific colors of Discus in which its difficult to keep/retain its color? I have heard Yellow for example. ..because most foods have a red pigment thus they turn orange or Whites that turn brown.
Discus color change…. Is it true they will hold their color once an adult?
What discus size is considered adult? or at what size will the retain their color?
Thank you in advance
