I kept them for over two years before letting them go when I decom. I got them around 2" & 2.5" and towards the end they were orange in color. Fed them with Ocean Nutrition and New Life Spectrum Pellets, and mysis marinated with vitachem, selcon and garlic express. Like Bulldozer said, the important thing is to have them healthy. I thought I fed them with the best stuff already, but if they are fading in color, something must be wrong somewhere right? Are there any ways to keep/improve their coloration in a way that doesn't harm them?
