Bloated belly on neon tetra?

Hello all! After today’s feeding I noticed one of my neon tetras’ abdomens is swollen? He didn’t eat an abnormal amount and is being just as active as always with the rest of the school. Tank parameters are normal and temperature is fine. If I could get an opinion on it that would be fantastic, I’m thinking it could have been overeating that I didn’t catch or he could be a she carrying eggs? Thanks for the help! (he is the top fish in the picture)

What size tank are they in? From the picture it looks small and neons need at LEAST 10 gallons but prefer more as they are active fish, how many do you have? neons are schoolers that prefer groups of 5+. If they are from chain stores such as from walmart, petsmart, petco ect they genetics of fish from chain stores tend to pretty poor but for neon tetras especially because they are overbreed and crossbreeding in a small population of fish cause weak genetics. If they are in a small tank, kept in poor water conditions, kept with agressive fish or kept in a school smaller than 5 it could be a sickness brought on by a stress weakened immune system, if the fish are from a bad source odds are they are already weakened genetically. IMO if all other conditions check out i would work on water changes more often and see if that clears it up. If it is carrying eggs the odds of seeing babies is most likely very low.

(keep in mind i had 6 from petsmart, kept them in a 10 gallon, perfect water conditions, after 1 year 3 left, after 1 year 2 months 2 left. They looked the same way yours do and they all died within a month of it happening :( rip)

Over Stocking Only Becomes A Problem For The Fish When They Can Feel It, But It Becomes Your Problem When They Feel It.
