Look at Pygmy Cory's for your tank.
I don't think so. Very different fish.
The three dwarf species will be fine in this tank.
Corydoras pygmaeus (pygmy cory)
www.seriouslyfish.com
These tend to swim more in the mid tank region than most cories
C. habrosus ( salt & pepper cory, not to be confused with peppered cories)
www.seriouslyfish.com
C. hastatus
www.seriouslyfish.com
Pygmies are the most common in shops; I've only ever seen hastatus once.
These all need a group of at least 10 and sand on the bottom of the tank. A 24 inch long tank is big enough for a shoal of 10. They are also soft water which which is why other members have asked for your tap water hardness.
Other species of cory grow bigger than these three and would need a bigger tank.
[It has been suggested in another post that false julii cories are dwarfs - C. trilineatus is not a dwarf cory]

But it stays small which is the main pointThe three dwarf species will be fine in this tank.

The three dwarf species (C pygmaeus, C. habrosus and C. hastatus) grow to a maximum of 3.5 cm.
The next smallest is C. panda (5 cm)
Other cories (including C trilineatus and C. julii) grow at least 5.5 cm with some species growing to 6.5 or 7 cm.

That’s very inaccurate julli corys don’t grow larger than 5cm plus they have the best pattern compared to the suggested three, I have grown and bred them for years and these are my observations

C. trilineatus have the potential to grow bigger than yours did. We should stock a tank based on the potential size of a species, then if they do realise that potential we do not need to buy a bigger tank.
To answer the questions posed in post #1. The substrate material is not mentioned, and for any Corydoras you will want a non-rough sand. As for species, the three "dwarf" species mentioned by @Essjay would be ideal, but we also don't know the water parameters. Other species which will be larger are not ruled out; most of the species in this genus are active in their constant foraging for food, but not "active" in the sense of upper fish requiring longer swimming spaces. Upper non-cory species, especially the "nano" ones like Hyphessobrycon amandae (Ember Tetra), Nannostomus eques (a pencilfish) or one of the dwarf rasboras in the genus Boraras are suited as far as space is concerned, but let's sort out the water parameters first.
