so i recently bought 3 blue star leopard wrasses, qt them for 2 weeks and were eating pods and slowly started to eat frozen mysis and brine. so i put them into the dt and they were hiding for a few days then they started to come out during the lights were on and were eating really well fed them extra pods when they were out to graze. then out of no where they all disappeared, didnt see them at night or early morning. checked everywhere around the tank and found nothing, then one day i saw one in the corner looking kind of startled tried to feed it and it ate a little bit, then next day it was gone again. its been about 2-3 weeks. has anyone had wrasses just randomly show up weeks or months later??
