Jumpers
I have had a number of fish try carpet surffing...going down the over flow...
I use a sock at the end of the overflow for two day, then remove it, anyway on my old 150 all is normal after a water change until I went to remove the sock you guessed it one fairy wrasse [ DOA ]
I had Marc build a black acrylic cap for the overflow box...no fishies or any other critters down the overflow...it also keeps light out...no more slime to deal with.

The cap is on my 120
