My Fire red Yuma that was looking healthy has suddenly been closed up for a few days. Is it possible the algae is bothering it? I tested nitrates and they were 0.2 ppm, my hunch is that the newly introduced peppermint shrimp were harrassing it. (Its a baby so its not even as wide as the plug when opened up.)
