HaHa. I love this. Another Paul B doesn't know a fish from Bernie Sanders thread.
In the almost fifty years my tank has been running I have had numerous tangs, acanthurus, hippo, sail fin, yellow and the stuff astronauts drink in my tank. I also used to keep mainly puffers and eels. I find those fish boring now and only have a hippo tang as they are really cool looking and have a little personality, unlike most tangs that just swim around going "Doot Da Do, Doot Da do" and waiting for the tang in front of him to decide to turn or eat. ;Wideyed
They die of old age as they should and never get ich.
I can answer this as I have been in this since the 50s. The saltwater hobby started in Europe but came to the States in about 1971. I think it was on a Tuesday and I was there waiting to buy the first blue devils and dominoes that arrived here. (I speak on this)
In those days we had authors like Burgess, Axelrod and Robert Straughn. Straughn was my mentor but I always disagreed with the other two even though they have more degrees than thermometers.
Quarantining was always in style because we didn't know much about parasites, there was no liquid copper,
(we used copper pennies and copper scrubbing pads)
But most importantly we didn't understand the role bacteria played in the fishes immune system.
Also, our tanks were filled with dead coral skeletons as live coral was not available. WE would remove the dead coral weekly to bleach it so it was nice and white.
The fish hated us and always had ich, so much in fact that we had to continuously keep copper (pennies) in the water.
Our tanks were not very healthy.
I discovered in about 1973 or so that If I fed the fish something with living bacteria a few times a week, I could eliminate the copper. I used live blackworms and since about 1975 or so,my fish have never had a parasite or anything else.
And to me, "to Quarantine is irresponsible." It's like that boy in the bubble. He can live in there forever as long as no one enters who also does not live in a bubble and if Nancy Pelosi sneezes near that bubble, he will die.
A quarantined fish always needs to be in quarantine and never have contact with anything with any disease bacteria on it. Is that normal? In the sea fish always eat live prey or seaweed with the associated bacteria and parasites. I have been SCUBA diving for 50 years and never saw a fish in the sea with ich, velvet or anything else.
It is much more normal to have a tank where diseases are a non issue and the fish never get sick and only die of old age. If you ever have a fish that dies from anything else besides jumping out, starving or being bullied, you failed. Sorry, but that was your fault.
Fish should never get sick and if you have a tank where disease bacteria, parasites and vintage Linda Ronstadt music is played, they will live forever.
I have some 28 year old fish along with 10 year old copperband and very old mandarins, pipefish etc. that don't worry about such things. Yes, even tangs, puffers, manta rays and everything else.
My fish always eat and never have to be coddled. Why is that? Am I the smartest fish keeper? I doubt it. Best looking? Well, maybe
If anyone on here has old, spawning fish that have been quarantined raise your hand. Old fish are not 5 or 6 years old.
How many people have quarantined fish that die only of old age? How many quarantined tanks have never had a disease? How many fish die in quarantine? Don't believe me, look at the disease forum. They usually start out like this:
"I bought such and such a fish and it was eating linguini in the store. I brought it home and before acclimating I dipped it in fresh water, then put it in Prizapro then 60 days in quarantine.
After a week it started swimming near the top of the water. Then it got spots so I dosed copper.
It stopped eating, and the next day it croaked so my wife divorced me and ran away with our butcher even thought my wife is a vegan. "
But when I get a fish, I bring it home and after 10 minutes of acclimating I put it in my tank. He immediately eats and in 10 or 15 years exhibits senility (depending on what type of fish it is as pipefishdon't live that long but clowns live into their 30s)
The thing dies and my wife is still with me after 45 years but she is not a vegan.
Oh finally you chimed in. Sorry if my thread feels unnecessary. I could have posted in your thread but the last comment was back in July.
