Planting

For a 10-gallon tank. Choose your tank's size and the numbers follow it.

No plants: The clean look. Plastic plants count as none.
Lightly planted: A touch of green, about 1–2 plants.
Moderately planted: A proper green backdrop, about 3–4 plants across the back and the middle.
Heavily planted: A jungle. More than 4 plants, from a carpet in front to tall ones at the back.

Filter

Most filter boxes say which tank sizes they are made for, such as “20 to 30 gallons”.

Little or none: Running light, with no filter or one made for a smaller tank.
Standard filter (the default if left blank): The usual, one filter whose box includes your tank’s size.
Oversized or sump: Going big, with a filter made for a bigger tank, two filters, or a sump.

Water changes

How often some of the tank’s water is swapped for fresh, treated water.

Monthly or less: For the laid-back keeper.
Weekly (the default if left blank): The classic routine, and the one most keepers settle into.
Twice a week or more: For the full-time fish keeper.
