The red one stays red. She lightens up to a pink when she courts one of the males but thats about it. I have a small colony of 6. And all the other ones are brown.
They are fed twice a day, they take frozen mysis, I prefer PE. I have a copepod population of Euterpina and culture both T. Iso and Tetraselmis to feed to the Euterpina. Originally I started the copepod culture for baby seahorses (I have multiple species) and although the fisheri take them, its just really a big hassle since they can take bigger foods. Since I can't seem to find live brine around here anymore I started a culture from bbs and at least once a week I enrich adult live brine with one or more of: t iso, tetra, vitamin c, astaxanthin, algamac, and sanolife probiotics.
