Any species suggestions?

Depending on the species of cory, some will get pretty large. Remember to think about the adult size of the fish. (By large, I mean 3 inches (that's big for me)).

The corys will add lots of entertainment value as well.
 
Dont do a waterchange in a new tank for 12 wks. Try to find someone with a established tank and get some gravel or old but fresh filter cartridge or a sponge/box filter or just 3g of water

do you have any kind of facts to support that? water changes are one of the most important factors in keeping fish - there is no other way to remove the hormones, physical wastes, nitrates, and other dissolved solids that build up in the tank and harm the fish. they are especially important during cycling and whenever new fish are added, as ammonia and nitrite buildups are known killers of fish, and can cause physical harm at non-lethal levels as well. gill damage, etc. . .

as far as seeding the new tank - that is a good idea, but the good bacteria you need are not found free-floating in the water, so getting water from an established tank does nothing for your cycle.
 
Thanks Scott-kim,

I've discovered that the AC 110 is too much filter but that's what I've got. It's brand new and I bought it thinking I was going to get a 55gal. My buddy just gave me his old, empty 30g so I was going to limp by. Any suggestions on how I could make this work? I could turn it all the way down and try to buffer the flow with some sort of obstruction. Do you think that would be sufficient or should I just buy another filter and be happy with having a setup ready for ANOTHER tank. LOL

Can't have too much filter! :)
