I checked my notes and sure enough, the green neon tetras that currently occupy our Spec V (along with the red cherry shrimp and a horned nerite snail) are turning two years old!
We put them into the tank on 8/8/14. I guess they were at least a few weeks old when we got them from the store, so they are very close to two years old. I’m excited that they have survived this well and I hope I don’t jinx them by writing this post.
We have had a few casualties. We originally put in seven, but two died around December of 2015. One had a large tumor develop on her back and she succumbed to death eventually. Another mysteriously disappeared around the same time. I didn’t have to deal with fishing out the dead fish because of our wonderful red cherry shrimp. They are a wonderful crew of little morticians, lovingly disposing of the dead for us. Nice!
The Green Neon Tetra fish that we have (paracheirodon simulans) has a listed lifespan that is the same as many other tetra type hobby fish, around 5 to 10 years. So 2 years isn’t anything to write home about; however, I was uncertain how they would do in around 5 gallons.
Hopefully they will keep chugging and we will keep enjoying them for a long time.
I’m interested to hear your comments: what is your oldest fish? How about the oldest fish for those of you with nano aquariums like the Fluval Spec’s?
