next fish to add?

Actually Cory Catfish are some of the Amoured Catfish. I have a cool little encylopedia for kids that shows a great pictures of cories labeled as Armoured Catfish.
 
Also, I have read where regular cories are considered "armored" but these are definitely not the same thing. The catfish I am referring to are Callichthys callichthys

I hear they do well in a tank around 30 gallons are are not very aggressive, but I want to make absolutely sure they wont bother my danios
