I'm nearing saying I'll go for Cardinals as I've heard Neons won't do well in my new setup. I think I'm going to contact the guy from The Tropical Fish Shop as you have, and ask him how much it will cost if I bought my whole stock from him. Surely I will save some pennies there
That won't change with cardinals. Cardinals, neons and rummy noses are the one's which consistently do less well in a newer set up. Sorry to bust your bubble there!
I have done my fishless cycle and added my cardinals with no problem. I dont think they are as touchy as their reputation may say. I have heard of quite a few people adding cardinals to a new (cycled) tank
