hey ca2or, don't feel bad it happens to all of us, I will share just 2 of my many losses, I've had 2 super male lineatus wrasses jump out of the tank, even with egg crate, thats $600 retail, I was working at a fish store at the time so it was $200 each for a total loss of $400 :(. I also a a male scotts fairy wrasse from vanauatu die for no apparent reason, another $175. I don't by to many fish anymore, just corals because they are so much easier to keep!!
