Bought a Six-line wrasse yesterday and acclimated her. She was fine, looks healthy and swimming all around the rockscape underneath around it observing and picking at copepods, etc. My pistol shrimp is all underneath my rock work burrowing. Lights been on for 3 and half hours and now I can't find my wrasse. Looked last night to see if I could see where it made its home. Couldn't find her. So I'm guessing the Pistol shrimp made a meal out of it. Anyone else have or had this happen to them before?
