The larger (believed to be the male) is eating like a pig. I have had the lights off since they were first acclimated (yesterday). The smaller (female) will not show any interest in blackworms, shrimp, bloodworms or anything else for that matter. My water parameters are almost perfect with just a hint of nitrate. The temp is 80, and they are in a 75 grow out with Play sand as a substrate. I have noticed today that it looks like there "slimecoat" has thickened and sand is sticking to their discs tail and clasper area. Any idea why this may be? Also any tips as to maybe break the smaller rays hunger strike would def be appreciated.
