What truth are we missing here?
Yes, this is how it MUST be done for fish that have been in a bag of water for many hours! In that enclosed body of water, ammonia from fish waste builds up and the pH drops as CO2 builds up, which converts toxic ammonia to non/less toxic ammonium. Once you open the bag and let fresh air in (or worse, add water with pH in normal range), most of that ammonium quickly converts back to toxic ammonia.Many years ago a well respected knowledgeable guy working in an LFS told me he doesn't equalise water parameters when introducing fish to the store. All he did was to float the bags for 15mins before releasing them.
He assured me it was no problem for the fish and that getting it out into decent water quality asap was more important.
Since then I have always done the same with no apparent ill affects to any of my fish.
Controversial I know esp to those who drip acclimatise their fish.
Tell me why he and I are so wrong not to mix water before releasing fish into the DT etc.
Osmotic shock relates to the salinity of the water. Not an issue with freshwater fish.Yes, this is a dangerous thread. It very much depends on the fish, what's fine for a tang may not be fine for an anthias. And inverts are a completely different story since many are from tide pools and see frequent changes in salinity.
In the freshwater world, you would be a fool to do anything but scoop and dump discus fish - osmotic shock doesn't bother them, but they need clean water. But another fish from the same area, cardinal tetras, must be drip acclimated unless your water has the same hardness or you'll lose most of them due to osmotic shock.
Must check salinity for fish and inverts and adjust the salinity of your tank to what they are currently in if it's too far off...Same, drip acclimating is only more stressful, for coral and fish i temp acclimate and put in tank, don’t check salinity.
But anyone (including an LFS employee) who makes a blanket statement that you should always acclimate the way a LFS does when they receive a shipment is a person who doesn't understand the chemistry.
Quantitatively, how much is too far off?Must check salinity for fish and inverts and adjust the salinity of your tank to what they are currently in if it's too far off...
Yes that is very out of the ordinary. The breathing is way too heavy and the big gulp at the end is also unusual. Next it is a burrowing eel and would never lay on the sand it would dig into it or be swimming around. Finally it was on its side and upside down for much of the time.Sloke what a neat fish, haven’t seen one before. Does that behavior contrast with its behavior the next few days after? I wouldn’t expect an eel to lay across rocks like that with the gill action and mouth that way, it didn’t look pronounced stress but it didn’t seem like a lively eel poking its head only out of a rock, hiding and ready to strike on some prey either
how much of a contrast to normal behavior is that video? Thanks for posting. I don’t keep fish, only corals, so I never get to see stress event behavior in my home.
Where are those papers? I would be interested in reading about that.Do we all agree 100% unison that skipping acclimation and putting low salinity fish into reefs is physically stressful all the time, but many fish just tough it out
Surely we wouldn't think the zoo manager published and peer reviewed is wrong or trying to add undue work to the masses
Isn't he a fish scientist
Isn't someone with an awesome home aquarium not a scientist in the matter, even if they write in an entertaining style?
If a zoo would never do what Paul does, should we all do it anyway?
Who's tank here matches Paul's unique tank context? I'm not seeing anyone advise differences to new tankers, I'm seeing the 5600th iteration of that home tank picture and writing that contradicts Jay just like the disease posts, in his forum.
It's easy to shape all outcome perfectly reported when our own reefs are the proof. Imagine running a forum where other people's tanks and reports are available, I would use what a zoo uses in that case.
That's kind of a loaded question ... Don't you think ?Do we all agree 100% unison that skipping acclimation and putting low salinity fish into reefs is physically stressful all the time, but many fish just tough it out
