How long can a tigrinus survive in a bag

  • We are currently upgrading MFK. thanks! -neo
Good to hear. Looks like it's going well so far, I think if you get him through the first few days you are pretty much in the clear.
Maybe post some pics when you get a chance.

... and plop it into my bucket of water.

Never ever heard of any fish suffering a shock by jumping in warm water. Temp acclimating is just another waste of time while leaving the the fish for more time than needed in the bag. Not to mention opening the bag and leting air into it or even mixing tank water with bag water...

Hi Raymond! You do realize you are challenging the convention, don't you? Pretty much 100% of people on MFK acclimate their new arrivals, as do all LFS I know of, at the very least temperature-wise.

Yea, I know, I've heard of Giordano Bruno and Copernicus...

Perhaps if you worded your post in a way that lets us understand you are only voicing your own opinion and not professing an absolute truth, we'd get you better. Perhaps, this is how you meant it. I don't know.

From my own experience in the last decade, I killed a few dozen of various fish in short order by skipping or rushing through acclimation, either within minutes or days.

Temperature shock, osmotic shock, pH shock, etc. have been well studied and reported in scientific literature.

But for all I know, you are new here, and I might be talking to an ivy-league Ph.D. in ichthyology and getting myself in trouble :)

It sounds like you want to be helpful to others. May I suggest then re-posting your take in a new thread in General Aquaria Discussions board (but being a bit more careful with words) and then we all can have a nice, edifying discussion and actulally hear from verified expert-members on MFK. Buried here in this obscure thread, this will not get the attention we need to figure out what's what.
 
You’ve never been to a wholesale operation then... straight out of the bags after hours on a plane and into baskets with no water for sometimes a few minutes at a time while they unpack and then plopped right into holding tanks.
I dont acclimate fish anymore and never had a loss

There you go. You already have a proponent, Raymond!

I am glad to learn from anyone. And I've never been to a wholesale operation. Are you stating all wholesalers treat all fish this way? Somehow I doubt it very much. From those that cost $0.01 each to those that cost $100 each?

What fish do you not acclimate and how many have you done in this fashion over what time that you never had a loss?
 
I’m in no way knocking anyone that does acclimates I just personally don’t anymore. I don’t keep hardy cheap fish either. Ive had no problems in the past with discus, wild caught Fronts, rays, countless aros, dats etc

Just don’t have time or patience for a slow acclimation anymore. Done it this way for the past few years with hundreds of fish
 
Hey Viktor, thank you for your kind words. I didn't mean to be a smart ass, I am not prophet to anyone either, not my intention. Your are right in your points, I am only talking from my own experience. Granted my water is rather hard and high in PH so the plop and drop method is easy coming from low (water enclosed in a bag) to high PH. Temperature wise please note I said "warm" not "too hot water". Extrems were never good.

Please see this video so you can have a different point of view and maybe understand what Eatsomekiwis meant:
 
Cool video. Thanks!

Two knee-jerks: they place the discus into the first tub with the shipping water and then move them into a smaller, taller tub (I suppose the equivalent of the basket in eatsomekiwi's post) that (1) does have some water, not dry as eatsomekiwi said and (2) either I missed it or they didn't say what kind of water is in there, so I assume their tank water, no?
 
Hello; Watched the video. Some things came to mind. I get that they are working with large numbers of fish and have to move along. The fish have been in bags for a "long time" as one fellow mentioned. May be the risk of doing it the way they do is less than taking a longer more "traditional" approach and leaving the fish in the bags that much longer.

Another guess is there are some details we just do not get from the video. Would be interesting to know how the system evolved. Maybe like I have done over time and learned from mistakes. By that I mean how did they learn to lower the tank levels on the larger fish, trial and error perhaps.

While it looks fairly casual my guess is they have done a lot off advanced planning. I did not see heaters in the tanks so perhaps the building itself is heated. ((or cooled depending on where they are.) They may have taken some sample temps from the boxes/bags and know how close the temps are.

I must agree the system used worked. Even so I will stick with my more traditional method of acclimation. I have plenty of time and will not be unpacking 500 fish.

Had a fellow come by to look at my roof today. We got to talking cars and trucks after a phone call from a dealer I have been haggling with. He is interested in my Sentra for his daughter. I was telling about how I do regular things in addition to oil & filter changes. Such as siphon out the power steering reservoir at the same time as each oil change. Flush the brake and hydrolic clutch every two/three years. Change transmission fluid on a regular basis and such. The guy kept telling me how he never does most of those things except oil changes and never has any problems. I told him that yes few do it my way and many do not have many problems. I do know after working on many cars and trucks that some have problems that could have been avoided. My 17 year old Sentra is in good shape.

To each his/her own way of doing things.
 
Right. Thanks for that. Yea, I forgot to state that yes, their method works. Albeit, just like Jeff above, I don't know if the shipping water was close in all parameters to the receiver's tank water, most importantly temp, pH, hardness, and TDS. If so, that'd be one conclusion. If not, that'd be a completely different conclusion that yes, indeed, the acclimation we do may not be necessary. For these discus, their source, and how they were packed and shipped at least.
