thanks for the reply. I just did a 30% water change and everyone is eating like usual. I did not see any dead today fortunately.

"Lifespan:6-8 years"


https://www.fishkeepingworld.com/rummy-nose-tetra/


"Approximately 5-6 years."


https://en.aqua-fish.net/fish/rummy-nose-tetra1


"The average Rummy Nose Tetra lifespan is 5 to 6 years in captivity. However, some owners have managed to help these fish live up to 8 years (great genetics comes into play when exceeding 6 years)."


https://www.aquariumsource.com/rummy-nose-tetra/


The lifespan of Rummynose in wild:



"In the wild, Rummy Nose Tetra lives typically for around eight years. However, in captivity, they generally have a lifespan of about 5 to 6 years."

So, no, the fish did not die of old-age.

Bump:
Also, lets assume this species reached its maximum age at 2 years ( it doesn't, but lets just use it as a hypothetical) the likelihood that all would die of old age in the same week is highly improbable. Some would be stronger than others and would be susceptible to disease over a period of months, not days.

It is probable, however, that their immune systems are depleted from long-term exposure to improper water parameters and all were susceptible to whatever pathogen has killed them. . Long-term stress is the leading cause of disease in fish.
Rummynose is similar to cardinal tetra in sharing the same habitat and caught in large number for the hobby. Cardinal, similar to Rummy and most small tetra, is profiled to have 5 year life span in captivity, but in the wild they are annual fish.

You can generally get 3 to 5 years out of captive bred tetra starting from juvenile size, but wild caught tetra are more delicate, and caught at full grown size, so getting 2 year out of Rummy in captivity is near the top of their life span. It’s not uncommon for fish to die near their life span at about the same time as what kill aging fish can be the same cause due to old age susceptibility of diseases.

This ends here. The OP has all the commentary from you and I they need to look up their own information from here. Go argue on someone else's post.
