I am so jealous of the reds I see in other members galleries. Gorgeous bloody red coloration. Mine were like that wen they wer like 2-3in , now they are mostly greyish greenish with hints of red near the gills. Sometimes the redness shows a little more but its temporary ( few minutes ). Whats up with them? I keep up with my weekly or bi-weekly water changes and they are fed once a day ( shrimp or hikari gold ciclet pellts with color enhancers). Why has their color faded so much? Any help please?
