Does the runt of my green neon tetra school look a little odd?

@Chick-In-Of-TheSea Does this look like your black neons?

Indeed, in body shape. 

The fish looks washed out in color. Looks like a cardinal, but pale.

Watch behavior. If he’s the runt, he may very well get picked on. ESPECIALLY watch him at mealtime. Is he being out competed for food or nipped by the others? It’s easy to miss when there’s a lot of activity. I’ve found they have a pecking order.  I don’t believe it’s a sunken belly (illness), but it could be hunger.

Also, how many tetra are in your school?

I’ve bought neons twice and each time one was a little thin so the belly line was flat like that. I do QT so it could be that being dewormed helped but I feed them frozen baby brine shrimp in QT and I definitely think that helped them get chubby. You might want to try some and see if that helps.
