I found my New Guinea Wrasse on my kitchen floor this morning.He usually get up very early before the lights come on in the tank.I think he went over by where the Royal Gramma sleeps and the Gramma attacked him.I through him back in the tank with a few words LOL.He was laying life less on the bottom for a minute then he started to breath again and move his eye around.After about 20 minutes i tried to pick him up and he just took off swimming .I took off the cover off in the summer and did'nt put it back on .My bad..!So guys keep the covers on LOL.
