How long might you expect cardinal tetras to live for?

Just that really. The thing is that we got 'large' ones so they wouldn't be eaten when added to the tank so I don't know how old they were when we got them. Is there such a thing as an average life span?

I thought this was about the pope's replacement!

Grin SPB.

I would expect 5-10 years for cardinal tetras. They would probably be close to fully grown by a year.

Can't comment on the Pope's replacement but if his name is Cardinal Tetra then that might be enough to convert me from atheism to Catholicism.

Brilliant SPB!!!

Thanks Eau. Found a few articles on line which all seemed to say 1 year in the wild but 3-4 years in an aquarium - you obviously keep yours amazingly!!

3-4 years? Nah, they live way longer than that. This is a pretty reliable list of life expectancies. Cardinals aren't on there but neons are and other similar-sized tetras. Really I would expect 5 years at least. 1 year in the wild is probably because they have to share with piranhas Grin
