Help with overflow.
My overflow is basically a pipe with slits in it. Recently my cleaner wrasse has gotten sucked into it down to the filter sock in my sump and died. A few days later my chromis disappeared. I just found him today in the sump (I took the sock out). How can I prevent this from happening? Both fish were healthy and have gone very close to the overflow many times so I was surprised that they got sucked in. I was thinking about using a plastic screen and rubberband.
