    Neons are egg scatterers, they don't get pregnant. Try feeding a frozen pea or two, it might be obstipation

    Also if it did drop eggs, they wouldn't last long in the tank. Other fish would eat the eggs. Also the eggs are light sensitive, very low likelihood of fry showing up in an aquarium. Would need to black out the tank for even the possibility of it happening.

    Just to add, I really doubt you could manage to get viable eggs and hatch them, Neon breeding is almost unheard of in the hobby, most are wild caught. Could just be a greedy fish, as suggested feed a frozen pea (defrosted, deshelled, squished a bit).
    My therapist says I need a bigger tank . . . . .

    Most neons, at least on the European market, are farmed in south-east asia. Wild caught neons are very difficult to get unlike Cardinals.

    Wouldn't say breeding is unheard of. When I started in the hobby in the mid-1980s I got a bunch of old magazines from the 1970s and in one of those was a breeding account. Problem is that they need extremely soft and acidic water to get in the mood and that light kills eggs and small fry. pretty much describes what I read back then. So it can be done, it's not overly difficult but it does require some effort and it will not happen in the normal tank.

    Since everyone has already chimed in about your odds with the eggs... I'll just add that the word for a fish that's full of eggs is gravid.

    This is just concurring with previous advice for the most part. From the photo I would suspect that is a female, they are naturally rounder than males, but the peas someone suggested won't hurt just in case, as photos can be misleading.

    As talldutchie mentioned, wild caught neons are pretty much non-existent in the hobby these days, unless someone imports them specifically. Decades of captive breeding in SE Asia is believed by many to be the reason for the health problems with neons now. They certainly are genetically weaker than wild caught fish.

    And the advice on breeding this species is correct too. Very soft and acidic water, and darkness. It is very unlikely to occur (to the point of seeing fry) in community tanks. Same goes for cardinals. Of all the characins I have kept over many years, these two species have to my knowledge never spawned.

    Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

    Think it's indeed a healthy female.
