Neon tetra has a lump please help

[Captainrivera]

My neon tetra has a weird lump, no clue what it is. I need help to identify the problem. I do water changes every Sunday, ph, 7.5, temp is 77, nitrate 20ppm, nitrite is 0. I have snails and shrimp, and live plants. Floral lighting. 26 gallon tank. 9 months old Please help, eats and swims normally

Im not sure thats odd

Really? None of the other tetras have that bump on its belly and it's staying way smaller than the others

when they're smaller the distended stomach from eating is more apparent. Keep an eye on him, but to me that's what my neons look like when they eat a little too much. You could try feeding a little less.
