They make sponges that go on the internal part of the pump to prevent death by suckage. I have the same problem with bangaii cardinals and powerheads. I also had one sucked into the eductor. That was unpleasant.

How long did you have the fish?

I've had mp40s for years and never lost fish to the pump. Unless they are weak on their way out they do end up stuck in the pump but in my opinion a healthy fish should't get sucked in to the pump.

The Fish are probably weak if there getting sucked up at mid speed.

I've only loss one fish to a vortec. It's was when I had mp60s on my 300. When I was doing some maintenance on the vortecs and had them turned off. A black blenny swam into on of the wet side while it was off. I didn't see him in it and when I plugged it back in the prop chopped him up.
But my tangs loved to swim in the current when my mp60 ramped up to 100%. So I wouldn't see a 40 being to much flow.

I had a juvenile chevron tang get stuck to an mp-10 once, but I just bought the sponges that wrap around the wet side and had no losses after that.

Sounds like the fish might have been sick or weak. I'm running 2 MP60's on my 120 with out any problems

Probably sick fish. Running mp40 at 100% max on reef crest mode on a 60x24x24 tank no problem at all, with about 20 fish.
