all along we thought they were piscivores...
thanks for sharing.
Well, they certainly will eat fish, but it seems that crabs must be an easier target. What do you think of trying to feed small FW crabs to my polys?

I'm surprised too that they didn't find identifiable fish remains. I would imagine a fish takes longer to digest than an insect.

Did Dankwa mention what size the sample sens were?
