Why do some do so.

[Randy Holmes-Farley]

A fish may have enough of what it brought with it in the wild to survive your harsh unforgiving environment

That was my thought as well. Any “immunity” a fish has before qt, it likely has after, along with a lower load of disease vectors. Not many types of immunity are lost in a few weeks. I agree qt may weaken them, just as many harsh human medications can.

This is probably true, we don't know. But if those fish are transferred to a tank that was quarantined, there should be no parasites in that tank, and in time, those fish will have absolutely no immunity to parasites. Of course they will live like that as long as no parasites ever get in and no fresh shellfish are fed or any fresh foods.

Issue I see is if a fish comes in emaciated and weak , their immune system is not at 100% . Yes removing stress is very beneficial . But the fish can be overcome quite quickly by the ecto parasite . It takes time for the fish to recover from malnutrition . Just removing stress doesn’t automatically mean that the fishes immune system will recover quickly . Some of these ecto parasites outside the body are not within the corpus and then not subject to the fishes immune defense system . It takes time for the fish to recover and especially if it is stressed . So removing stress is important , But if the parasite overwhelms them with sheer numbers then not much they can do . Velvet and ick can do this . Now do other organisms prey upon the tomites of the parasite? Possibly yes ? Apocyclops is an example of a copepod crustacean that eats s wide variety of organisms . So are there others , more than likely yes . Can these older systems harbor these predators ? More than likely . Do we know what they are ? Probably not . Do other aquarists with new tanks or tanks without actual live rock have these organisms ? Maybe yes maybe not . Does my QT tanks have these ? Definitely not . Does my display tank have this . Definitely not . So I am not in any position to tell others what to do . But I do recommend QT to avoid parasites from coming in . Same with coral . If you don’t prophylactically treat and QT . You risk all sorts of bugs . Does everyone have wrasses , crabs , gobies and what other predators that can handle all of the ecto parasites ? Probably not . So a word to new aquarists , I would recommend QT , strive for one of these tanks that are greater than 10 years and then entertain the idea of no QT . Again this is my 2cents if you don’t agree that’s ok . But it is good to present all of these choices .

I agree with that. New tanks are never healthy, especially if they were started with dead rock and asw. I'm not sure I would wait 10 years to have a natural tank but as long as somewhere down the road the fish could achieve immunity, that would be fine.

Achieving immunity IMO should start at the beginning when first setting up the aquarium. Live rock, sand on the base with a few cup fulls of sand from an established tank if possable. Sand from a reef tank where no meds have been used. That dosen't mean your tank is mature as IMO that takes around a year or more..

Feed any fish live or frozen foods not hamburgers.. I mean dried foods. A reefscape should be just that not just a handful of rocks looking pretty. Lots of rock with.nooks overhangs and caves to help make the fish feel secure. The list goes on and if course just my opinion based on my experience.

I'll chime in. I don't have as much experience as some on here, but i've been keeping fresh water since 70s and switched to salt water in 1990. For twenty years, I thought salt water fish were immune to parasites. I never had one get sick. But I only fed fresh seafood. In 2010 i came across my first forum at marine depot and that's the first i ever heard about quarantine. I still don't quarantine and my experience fits that of those also on here.
Back to topic, my last tank is nine years old, and i've never cleaned out the detritus. I keep my tanks a little different, i pump water up above the tank to containers that have macro and mangroves with carlson's surges, bringing the water back down. There was 3" of mulm/detritus in those tanks. I just upgraded to a 300+ gallon tank and all that mulm went over with it! I have 3 cut in half 55 gal drums over the tank with surges, macros and 9 mangroves as the filter.

Thats why they never got sick. Most people don't do that and that is the main reason we have disease threads.

Eureka! I found an Oxidator on Amazon. It’s smaller than the model that you recommended. However, my seaweed & shrimp tank is 15G. In reading the instructions, CO2 is initial byproduct which works for me as I had been considering a calcium reactor whose byproduct of CO2, I consider to be a source of carbon that will encourage ornamental seaweed growth. I hope.

What model have you ordered for your 15g the model D? As far as as I am aware no CO2 is produced by the Oxydator nor is it removed.

A long time ago I read the ingredients label on dry fish food and one of the main ingredients was wheat. I just dont think ocean fish should be consuming wheat. The frozen fish food sold in cubes is/was expensive. You can get way more just buying fresh seafood at the grocery store.

And that is the whole thing about fresh frozen and dry foods. The wheat and soy are cheap and used to bind other dried foods together and as fillers.

Sochting Oxydator D - Increase Oxygen Level in Shrimps Fish Tank Aquarium​

This is what I got from Amazon and clearly says for increasing oxygen. However, in reading Sochting Oxydator D instructions

PS: I must admit, I don”t understand their chemistry.

Harrr yes indirectly the Oxydator in fresh water with mud thats has CO2 bound up in it will release the CO2 by the peroxide acting on the mud.

Thank you for explanation. That works for me as I have ornamental seaweeds to consume the CO2 enrichment. I consider it a source of carbon.

Exactly why my dogs get fed 100 raw meat with organs and bones. Too bad I can't get seafood where I live so frozen food is the best I can do.

They do that to human food as well. I think that's why so many people have disease. I started eating a carnivore only diet 4 years ago and it cured every ailment I had. No more of the doctors poison pills. We need to treat ourselves like we do our fish.

Get you some, dog. I am still laughing. I have a 120 Great Pyrenees that thinks he is people.

For certain your furry friends love you.

Here we eat a lot of fish and other seafood. My family was in the seafood business.

Black linguine and shrimp.



Linguine and clams



Prepping for Manhattan clam chowder



Spaghetti and crabs





Oysters.

My wife went carnivore with me but she's Italian, like you Paul, and sure misses her pasta! That food looks amazing! Good thing seafood is carnivore!

Here's the new tank so far. Its been running a couple months. Still need to build the facade. Using a bunch of reclaimed wood to finish.
