Goldfish is torn up, but looks healthy?

[lmbauer2017]

So this is the second goldfish that I've found torn up. I have another goldfish, and I don't know if they'll eat a dead one. From my very limited knowledge this fish looks healthy. I previously found like 5-6 dragonfly larva that were easily as long or longer than the goldfish, and I thought I had caught them all. But then this fish showed up, and upon re-searching the pond I found 3 more big larva!

I just wanted to make sure that these were most likely the culprit and I'm not missing anything else. I kind of thought they'd eat more of the fish, but it looks like just the stomach portion was eaten. I killed the larva that I found (I have plenty of dragonflies in may garden don't worry!), and I suppose now I'll need to re-check the pond every couple weeks to make sure there aren't any others growing large enough to eat the fish.

Would you all say this is a good assumption? Or could the other goldfish just attacked this one? Or does he look sick and then just died leaving his corpse to be feasted upon?

Thank you!

Goldfish are not going to attack and kill another of similar size. May pick at a dying/dead one but I would lean toward consumption by the larvae.
