Cause of death?

[JoeBoxer]

Anyone have any idea why my Cory looks like he bled into himself?

No aggressive fish in the tank with them, just tetras and some small barbs and a red tail black shark. Havent see any aggression between any of these fish.

Thanks.

Have you tested your water, what are your current parameters?

 

[JoeBoxer]

Took it to LFS for testing. Said all is good. I know I should get a kit but I figured I'm just getting the hardier type common fish so should be okay.

Internal bleeding. Blunt force to the body. Have you question the other cories? The cory on the left looks guilty..."criminals always return to the scene of the crime"

 

[ehh]

I used to see this happen to a lot of guppies and smaller tetras.

I wonder if he choked on a grain of the sand or it cut him up inside or something. Have lost a bunch of fish lately just trying to avoid further loss.

suicide by swimming into decorations.

That or one of the fish has a baseball bat.

In my experience, panda corys aren't the most hardy. I wouldn't be surprised if he caught some weird bug and his immune system couldn't handle it. That or he was sick in some way and it just took his life.
The fish I originally mentioned were sick. I just never got a real diagnosis on what killed them.

I would say the shark did it. Red tails can be highly aggressive to tankmates.
