Lumpy Glowlight Tetra

[birdiefu]

I have noticed that one of my glowlight tetras has an oddly-shaped abdomen with two points on the bottom, but symmetrical side-to-side. The fish otherwise acts normally, eats well, and doesn't show any other lesions or signs of disease. I am not sure if these are possibly lumps due to eggs, or if it's something more serious (like neon tetra disease?) that must be treated/quarantined.

Tank has been inhabited for 3 months (fishless cycle previous to that), and is planted. Some tetras were removed about a month and a half ago due to one having a fungal growth. One danio unexpectedly died a few days ago, all the other fish seem okay.

Just wanted to update that the lumps are gone today and the belly is smooth again. I'm guessing either she had eggs or, looking back, I had just given them some frozen brine shrimp before I noticed the lumps, maybe she ate too much? Regardless, everything seems to be fine now!
