Skinny fish spitting out food.

[Roach182]

I have 2 fish that have gotten quite skinny over the last couple of weeks. One is a blood fin tetra that got that skinny in the the belly that his spine looks like it is curving, the other is a female guppy that is has really gotten thin. They bothe try to eat but everything they take in thier mouth they spit back out instead of swallowing. All my water parms are fine, and all my other fish seem quite healthy and happy. Any ideas?
TIA

Probably best to euthanize. Their bodies are shutting down so they can't swallow food. It could be TB or any number bacterial infections or even parasites. At least QT them to prevent whatever it is from spreading.
