What is this in my ADF tank?

[Random-storykeeper]

I noticed, floating at the very back of my tank, was a tiny bean-shaped like object. Part of it is clinging to the back of the tank. I tried to take pictures, but I couldn’t get a great angle. The thing is white and smaller than a fingernail and I can see some black specks on it or in it.

I have 3 ADFs and I have seen two of them mating before, but never saw eggs. From what I’ve seen, ADF eggs are usually more spread out, right? I don’t have any other animals in the tank, save for a few ghost shrimp many months ago (but I think they’re all dead at this point).

Maybe just an unusual looking piece of poo.

is it alive?

My bet is eggs or poop. But I have no idea.

Whatever it is, it appears to not be there anymore. Although I would be surprised if it were poop; I always thought that stuff would sink into the substrate.
