Serpae tetra eggs??

HI guys, I was wondering if any of you knew how to tell if your serpae tetars had laid eggs. The last time I checked the pH : 7.2, ammonia, nitrite, nitrate : 0. If anyone could tell me what to look for, I would like it a lot.

Most tetras are egg scatterers. Meaning the female swims wildly scattering eggs and the male comes behind fertilizing them. They wolud appear as separate little clear eggs.
The unfortunate thing is most tetra eggs get eatten soon after being laid by the egg layers themselves or their tankmates.

Would one of the parents become aggressive to protect them? If so, which one?

No because they just scatter them and then either eat them or forget them. They do not parent raise their fry.

ok. Thanks.
