1 still iffy but hopefull
2 going strong
All had very pink behind and around gills, though those in better condition, had less.
The water in this bag was pink (assume) bloody. The water in other bags was clear.
Again, packing, heat and shipping appeared top notch. Box seemed in good shape, too.
But these poor guys just did not do well.
Any ideas. Not after blaming shipper it appears they did fine from all appearances.
I am just curious, and interested what was the best triage I could have done, when I saw the ones that were clearly hurtin. Also is this indicative of internet buying. These were the first I have ever had shipped.
Thanks, as always, in advance.
Wild caught fish of nearly any species sometimes don't travel well and are often more sensitive to changes in water chemistry, and temp.
Best in my view to drip acclimate newly arrived fishes wild, or otherwise.
If these were indeed wild caught corydoras ,then they have already been subjected to Stress from being gathered from native waters and then shipped to where ever.
They are then once again caught ,and shipped to you, (more stress).
Drip acclimating the fish slowly, is about all I can think of to allow them to acclimate to perhaps very different conditions than those they were recently removed from.
Will say that nearly all corydoras are much more comfortable with neutral to soft water ,and temp not much higher than 75 degrees F based on my expieriences with them.
Never be afraid to check feedback from others who have purchased fishes from a particular source ,or ask questions such as ,,,how long the fishes have been in dealer's /seller's possession and what the water parameter's are in dealer's seller's tanks as well as what foods are being offered.
I have ordered many fishes online although not very many wild caught, and expect to lose maybe one or two due to the stress of airflights and or travel in a truck where boxes may get jostled more than we would like.
I seldom order fishes when the weather is cool and try and wait till spring although it is difficult for me.
