Fish longevity

[408Dartfish]

I’m curious to how long most the fish In my tank lifespan is? I know the clownfish can live 20 years. What about blue-green chromis, lawnmower & midas blenny, orchid dottyback? Thanks Dustin

Not sure on all of them, but I can say that I had some chromis in my last system that lived in that tank for 7 years and then went to a friends tank and at least one of them is still alive 3 years later. So that is 10 years.

Dottybacks can live 8-10 years.

Thanks for replies. Looking like average of 10 years.
