Which Cory's?

Which Cory's would you suggest for a 29 gallon tank. I just added my first fish last week (3 Serpae Tetras). So I plan on giving it another week before I add my second "batch" of fish. So a few questions:
(1) Which are the hardiest Cory's, and most fun to watch
(2) How many should I keep ( I've heard 4 is a good number)
(3) I've heard that Serpae Tetras can be aggressive, would they bother the Cory's at all, especially since they were their first and might feel 'territorial."

 

Aeneus corys both the albino and normal green are very hardy and fun to watch. If you have plants (artificial or live) and plenty of hiding places the Corys will be fine with the Serpae tetras.
The more corys the better they play and feel comfortable but you need at least 3.

Thanks! I'll look into those guys....

 

Here are some Cory pictures

 

Wow, they are really cool! Thanks for the pics! I especially like the ones second to the bottom, what are their names? (I also like the pandas!)

 

Corydorya elegans. The names are at the bottom of the pice. Yes I love the Pandas also, they are a little more sensitive than the others. but the other two I posted for you are easy.

There are bazillions of types of Cory, but most of the ones you commonly see in stores are hardy. Check out for Cory info.
