Are these parasites?

[abacabb]

I keep finding these at the bottom of both of my tanks.

Any ideas?

They look like some form of nematode. Whether or not they are parasitic is difficult to say because there are more than 20,000 species of nematode and the vast majority are harmless. Is your animal showing signs of illness?

Not really. I've just been noticing these creatures in both of my vivariums.

They look like cricket eggs to me.

They sort of do, we would need a closer photo to see the internal structure.

I agree. They are probably cricket eggs. I saw the exact thing in the bottom of my tank.
