That's false, but unfortunately a really common misperception in the hobby. And sadly, consolidation in the wholesaler side of the saltwater fish hobby means that there's a lot more disease to deal with than there was 15 years ago.
My bengai cardinal was found dead today.
Had that fish for going on 5 years.
That is the problem with not quarantining new arrivals. One fish brings in something and now fish you have had for years are dying. Which fish will be next? No fish go into my display without spending 90 days in my qt first. It really is just a small 50gallon reef tank so I can make sure they are healty first. Much better to lose there than risk the 23 fish in my main tank. I have 1 clown that is over 25 years in my care. Her mate is 2 years younger. My sailfin tang I have had for 24 years. My yellow tang is older although I have had it only 23 years myself. Previous owner said it was 4 years old when I got it naking it 27 years old.
This has nothing to do with quarantining or not. Although it can for other situations.
I rarely add new fish. Very rarely.
I just looked up the lifespan of the bengai cardinal. Mine was about 5 years in my tank and who knows how old when I got him.
Their lifespan in the wild is about 2 years. In captivity they can live longer but up to around 4 years. So I feel good about giving this fish a nice long life.
I don't know where you are getting your information but I have a Bengai Cardinal that is 11 years old and still very healthy. I have 4 fish 22-27 years old currently. When fish die of old age you can see it coming they start looking like an old fish. They slow down, lose weight, their colors fade and their fins become tattered. It does not happen overnight, if you are paying attenion to their condition. I have a wrasse that is going through it now. It looks like an old fish! It still eats and I make sure it gets extra food, but I know it will not be around in a month or two and I will be sad.
I use google
Unlike many other species of marine fish, the Banggai cardinalfish lacks a planktonic stage in its life history. The species has a short lifespan, reaching around 4 years in optimal conditions in captivity, and perhaps 1 to 2 years in the wild.

yeah, i read the link. the information is not exactly hard to find.
but i'm still highly skeptical of it. in fact, i've never seen any information on how those longevity statistics were collected. were they actual studies? if so, what were their controls? how did they identify and track individuals? how did they account for their variables?
i tend to think most of those estimates are about 15 - 20% lower than they should be.
-edit- i tried to hit their citation link, but it 404s.
Clearly that info is wrong as both mine are much older with my female being 11 years in my care and still looking good. She eas fully grown when I got her so probably 12 years old. My best guess is my name is at least 7 years old. I know other people yhat have had them 6+7 years as well.Unlike many other species of marine fish, the Banggai cardinalfish lacks a planktonic stage in its life history.

some people (like me) enjoy this hobby to get their minds off of other things. That's what hobbies tend to be for for some people.
Usually responsible adults who already have a ton on their plate to deal with.
Throwing guilt trips around saying a pet your responsible for should not be thought about because children are dying and people are starving is ridiculous imo.
Just saying. Your post is totally uncalled for and is just plain wrong in a hobbyist forum for salt water aquarium hobbyists.
