Tetra's are egg layers, so technically they do not get pregnant. Sometimes egg layers can become egg bound, but sadly I can't tell if that is the problem...sorry.
she has been eating a lot less than the others and she has a piece of poop stuck inside her analfin I have not seen her poop yetHow much has she been eating? What does her poo look like and how often is she going?
I'm not sure, but Gypsy13 asked if the fish looked bloated (she is blind) so I answered her. It could just be constipation, so maybe you could try fasting the fish for a few days, and maybe even feeding pieces of blanched pea, with the skin removed.
