I had a six line wrasse commit suicide. I think it was because of feeding. I
was feeding the tank and left the lid open, then went to do some yardwork. My
guess is the guy saw some food on the surface of the water and went after it a
little too fast. I've seen him bump his head a bunch, but that was when the
lid was down. So when I got back an hour later, there he lay right in front of
the tank. I tried to put him back in and move water thru his gills with no
luck (
