Obese tetra?

[Noviceafter2yea]

Hopefully I will have more responses from this forum.

I have a glow light tetra that is super fat and, as an egg layer, cannot be pregnant. I can't even tell its gender.

I can't tell when any of them poops, so I cannot see if it is just backed up. I have fed smashed peas in case it is constipation and then it might look thinner if it poops. What could it be?

14 gallon newly cycled for a month or a few days shy
No new decor

5 glow light tetras - 2 added yesterday, but this one was just as fat before the additional fish.
No odd behavior, 1 of the other original 3 is rounder than the others, but not like this.

If it is a female with eggs, what happens when they are not fertilized? I am pretty sure the environment is not optimal for breeding and honestly I have no intention of breeding.

Maybe he's finding extra food? I had a guppy like that

Side view which doesn't really do the girth justice, but is the best pic I could take.

He seems the least able to get to food and when he (she?) does, it spits most of it out.

To me that looks like an internal parasite.


May the force be with you.
