I'm going to Atlanta to meet some family members and I am going to the fish stores there to see what's what. I'm wondering if I am allowed to bring them as baggage...if it doesn't work, I will just buy them and ship them to my house so I can get them the next day. (though that will be costly.) But does anyone know if i can? Delta airlines to be specific. I'm on the hunt for the great retroculus lapidifer but I'm really expecting just ordinary neon tetras and common plecos and your generic common mbuna.....thanks everyone. And before you ask, yes, I will make sure to have a heat pack and oxygen packaged in the bag, along with double bagging to prevent leaks, Jeff Rapps style.
