I have a Trachyphllia that was flourescent green for about 2 months. I went out of town for a day and a half and it was almost completely white. That was Sunday today Thursday it is starting to get some brown patches on it and there is only a little bit of green left. He looks Ok bodywise he has just lost color. A couple of different books I have read said this is almost common, but they all have different results ok in 1-2 weeks, ok in1-2 months,death, etc. All water parameters seem ok PH a little low at 8.1 but all other animals are doing fine. Any ideas? Thanks Andy
