You can quarantine new fish together. Check the store tanks and don't buy either if there are problems in the tank.
As for the pygmy's, Corydoras pygmaeus
, they are fascinating little cory's. I have a shoal of six in my 90g, bought all they had when I found them. As Rohland said, they do tend to swim around a bit more than other species, though not as much as Corydoras hastatus
, another of the 3 "dwarf' species. Photo of each attached for info; C. pygmaeus top left, C. hastatus top right, C. habrosus lower photo.
By the way, I have found that stores sometimes get the dwarf species mixed up; I've seen "Crydoras hastatus" several times in different stores, but they are actually C. pygmaeus, and sometimes C. habrosus, but all three are identical in their requirements. Moreso than their larger cousins, the Dwarf Cory
's will endlessly browse every plant leaf or piece of wood in the tank looking for tidbits of food. And from time to time they will attempt to join in a group of characins as one of the shoal, or just playfully chase another fish (non-cory) for no particular reason. Quite active species.
