I'm inclined to say 3 at a time with a week in between, but the state of your tank will determine this better. Definitely do not add any until the cycle is complete and parameters are steady, if they are not already.
Thanks for your reply.
The tank has been running for 3 and a half weeks, and it finished cycling 4 days ago (ammonia and nitrite readings at 0 consistently for the past 4 days, nitrate at 6). The other fish are 1 dwarf blue gourami, 5 long-fin black skirt tetras, 1 black molly, 1 silver molly, and 1 mystery snail.
I am going to wait another week before adding any new fish, but I wanted to see how I should introduce the cories when I do get them.
