Goldfish are considered bottom feeders, meaning they often scavenge for food at the bottom of their aquarium or pond.
In their natural habitat, goldfish typically feed on plants, algae, and small aquatic creatures found on the bottom of bodies of water.

The term “top feeder” refers to fish who eat from the top of the aquarium, and the term “mid-level feeder” refers to fish who eat from the middle of the aquarium.
“Bottom feeder” refers to the fish who eat from the bottom, and “all-level feeder” refers to fish who eat from any level in the aquarium.
Additionally, fishes and snails both can be bottom feeders. There are some bottom feeder fishes and snails available including goldfish, catfish and nerite snails etc.
