YES! Plopp&drop if the fish come in distress! Completely forgot about this.From experience: if the fish come in, in really bad shape - breathing heavily and gasping at the top of the bag - just throw them into a quarantine tank without acclimation. Most wholesalers do this - and hope for the best.
I agree with that. You want to get them out of that water as soon as possible.From experience: if the fish come in, in really bad shape - breathing heavily and gasping at the top of the bag - just throw them into a quarantine tank without acclimation. Most wholesalers do this - and hope for the best. Otherwise I use a slow drip method.
I like to get the fish from the bag into the tank fairly rapidly as well. I usually <"pour most of the water out of the transport bag"> (through a net, I know that accidents can happen) and then submerge the bag, fish and residual water <"in the quarantine tank"> and hopefully the fish will swim out of their own accord as the bag fills with tank water. If they haven't slide them out after #5 minutes by gently lifting the bottom corner of the bag and slowly withdrawing it.if the fish come in, in really bad shape - breathing heavily and gasping at the top of the bag - just throw them into a quarantine tank without acclimation.
I ordered 4 air valves and 6m of silicone hose to make 4 hoses for the 4 bagsI've done 8 bags in one bucket before. You may need to lower the total water volume so that the drip can have more of an effect.
The only potential issue with apistos is that they are aggressive. If they're comfortable enough, they might fight.
It also depends on how long the fish were in transit. Internationally over days or nationally for at most a day or just two hours drive? With or without oxygen? And of course the parameter differences as well.I know several apisto shippers that warn that as soon as you open the bag it can produce ammonia (as fresh air meets fish waste); but other knowledgeable site strongly insist upon drip acclimination. No clue which method is appropriate and how much it depends on your local water (vs bag water).
Knowing how it works in the EU the fish will be in the same bag with the same water for 24-48 hours at most, unless something unforeseen happens. Also Glaser uses oxygen, so the retailer from which you buy will likely have the problem discussed above. If they send the fish to you just with pressurized air and not with oxygen the whole problem with pH and ammonia won't occur. But that is pretty much the factor I can not estimate as I don't know the retailer you buy from. If they say they ship with Oxygen you know what to expect.Personally I receive the fishes on Friday 22nd, this week my shop is closed because of the 14th of July, I just know that the fishes leave from Glaser (in Germany) and are reconditioned before being sent back to me in the south west of France, I will leave a message here as soon as they are in transit
Ok it's ok aquaterra-diffusion (the shop in France) uses air under pressureKnowing how it works in the EU the fish will be in the same bag with the same water for 24-48 hours at most, unless something unforeseen happens.

I think while the primary principles of that theory is valid, the effects and time frame over which it occurs is irrelevant to the situation. While the pH will rise as dissolved CO2 concentrations equalize with atmospheric CO2 levels, without aeration this occurs over hours, at which time you will have diluted transport water with a significant amount of tank water and any ammonia concentration that had existed is likely a moot point. The point is there won't be a suddenly spike in pH due to the opening of the bag - it takes time for unaerated bag water to off gas CO2. Prime in the bag water is not a bad idea, as ammonia levels will be high and it will help mitigate the harmful effects of ammonia faster than just the dilution through drip acclimation.I see. This is a different problem. Usually, the bags are not under high pressure.
What I'm saying is that opening the bag will release CO2 that has built up in the bag (from the fish respiring). The CO2 keeps the water acidic, which keeps most of the ammonia in the harmless ammonium form. When the air in the room exchanges with the air in the bag, the pH of the water can rise, so there will be more in the toxic ammonia form.
If you add water conditioner to the bag, it can minimize the stress of the ammonia. Just be careful to dose the appropriate amount.
That sounds reasonable, a couple points:I think while the primary principles of that theory is valid, the effects and time frame over which it occurs is irrelevant to the situation.
