Sand. Halichoeres wrasses bury themselves in sand at night to sleep. Its literally their beds so they can sleep. In QT, it's cheaper to do bowls with sand than cover the bottom of the tank with sand. Especially if meds are used, the sand would be have to be discarded.This may be a silly question, what is in those bowles?
Both. Metro starts possibly tomorrow for internal parasites. Nothing else unless needed. Depends on eating. It ate a little tonight before lights out. We'll see how that goes tomorrow.I employed the bowls of sand in my qt as well. Best of luck. U doing Observation or prophylactic?
