Only fish i ever lost to carpet surfing was a Yellow Corris wrasse. One of the first fish i bought when starting into the hobby. I was pretty devastated.
I actually lost him a few weeks ago. I was negligent and did not listen to warnings. I had no lids on the display. He was previously in a 55g tank, and went into a 105g, which is the same footprint as a 6 foot 125, but is only 18 inches high. Likely never had an issue previously because of the height on the 55g.
I went the very next day and bought 1/4 inch galvanized mesh. Built the frames from lumber, covered the frames in mesh, then coated everything in epoxy.
Not gonna happen to me again.
