I'm thinking that they might need to see how they are physically doing after such a long time in transit. I know I get cranky after a few hours in airports and on planes.
I was sort of hoping sooner as I would like to get them well settled before I leave for two weeks in February. As much as Kierstyn is up to looking after everything while I am away, I would rather not have something unexpected crop up due to newish fish. That would give them only two weeks in our tank.
I wonder if the shop would hold them for a month.... probably better here than there for that long I suppose.
My advice, after many years of acquiring wild-caught corys of many species, is to not get any until at minimum a week in the store. It is not uncommon for half or more of a shipment to die within a week. It depends upon how they were shipped. All the corydoradinae are highly susceptible to ammonia (and nitrite and nitrate, but it is the ammonia here).
When you do select them, make sure they are not still "iffy." If they are sitting on the substrate motionless, sort of on their side, fins clamped, they may not make it. If they are moving about, fins erect, they should be OK but you have to be careful with netting/bagging/shipping them home, and then acclimating them.
I know this is making them out to be the most delicate of fish, but the fact is we have no idea what they went through getting here, and I think it is best to assume the worst. I have lost many corys during the first few days over the years, until I started following this plan of waiting at least a week. The store should be willing to hold x number, perhaps with a deposit, or if they know you. Then when they die in the store, that is there problem and not yours.
