I don't have a sump but I do have an in the tank overflow that feeds the skimmer. There is a strainer in it so anything large does not get in it and go through the pump. Anyway a little while ago I noticed something in the strainer which is not really under water. It looked like a long skinny fish.
I removed it and noticed it was a small fish, probably a gobi since I have a bunch of them but hanging on it was a mantis shrimp as long as the fish. Both were dead as it may have been in there for a week.
I don't know if the fish got caught in the overflow and the mantis went in after it or if the mantis killed the fish and they floated in or whatever.
I have not put rock in the tank in many years and never put any store bought rock in. It was all collected by me in the seventees.
The mantis may have come in with the seaweed and amphipods I collect locally as a baby. I would have noticed an inch long shrimp.
I once caught a 6" worm under my gravel. God knows what is living under there. The Loch Ness monster hasen't been seen in a while.
