Dinosaur Bichir - What is this?

  • We are currently upgrading MFK. thanks! -neo
My guess is it's a pebble or something he swallowed all mucked up with poop, mucus etc.

Agreed, that is poo around something.

OP, change out the substrate to something smaller like #22 mesh size sand to prevent it from accidentally swalling gravel.
 
Its eating. Swimming normal. Lays by the thing that was expelled. The thing has opened and looks to be a shell of some sort. I’ll take a pic tonight.

If 40 years of movies have taught me anything, this is either just a funny looking poop, or a horde of alien parasites are about to hatch and infest and kill us all.

I for one welcome our new brain parasite overlords.
 
I am suprised whatever it is was able to pass through his intestines and then be able to be passed it self.
