That sucks, I was always afraid of the pipefish in a higher flow tank. I lost a mystery wrasse to a mp 40 when he swam in to hide when if shut off for cleaning when it restarted he was inside
. I got rid of my 60s as my tangs would like to see how close they could get to it, like you said some extreme undertow I had to pluck them off the side of it a couple times weren't sick just dumb still have the fish and that was years ago. Sadly he's not any smarter to this day.
