I have had these rcs for over a week now. Seems like they are happy and are foraging. They did hide from my fish in the beginning because my female cherry barb went after them but they have all calmed down now and I haven’t seen them chase them lately. I had two super red ones and the rest were less red! But now I noticed my big red female lost that intense red and has a tan line from nose to tale! And the tale is tan! What is this! There’s one left that I noticed that is red without that line! My ammonia and nitrates are always zero. I dose Nilocg thrive twice a week. Hope they can get that red back. Any ideas on how to fix this cause I miss how red my big red one was. I did have my chihiros rgb set at 57% when I got them and have recently lowered cause of algae. I do not use co2. I lowered it to 40%. Thanks for any help!
