20 Gallon (high) suggestions

[madison22]

I am upgrading from a 10 gal to a 20 gal high. I have 2 mollies both female and an albino Cory. Suggestions on what to add?

You know what I love to see in tall tanks?

Hatchetfish..

I adore the way they all group up right at the water line.

I'd get a school of them.

Hatchetfish might not be the best fish for a tall aquarium, because there is not that much surface space for them to group around. A better fish would be a neon tetra bunch, or a snail (but not at once - the tetra's eat the snails). Alternatively, some other small fish, like otocincluses or danios.

Fed up with the same old stuff.
I think Hatchets would be fine.

it is basic logic - hatchets stay near the surface. a tall aquarium has very little surface/volume ratio, therefore reducing the amount of space the hatchets have. Again, tetras, danios, other mid/low level fish.
