Common and Sailfin Pleco

Hypostomus plecostomus is also referred to as the Common Pleco. The Sailfin Pleco is a similar-sized fish as the Common Pleco, causing much confusion among the species. Small Common and Sailfin Plecos are about 2 to 3 inches in length, but others can grow up to 18 inches.

Loaches

Loaches are the most common bottom dwelling fish that come in several forms, sizes, and odd behaviors. For example, the Kuhli Loach and the Clown Loach are completely different from one another in size and temperament and the Weather Loach is famous for its sensitivity to atmospheric pressure. This species of bottom dwellers have compressed scales in the skin, which makes them sensitive to weather changes. Loaches eat snails so do not include any as part of the aquarium or they will be consumed. Yoyo loach grows up to 5 inches and requires a cave for security and to be kept in groups. Dwarf Chain Loaches are peaceful and need to be kept in groups, especially since their maximum size is 2 inches in length. Hill Stream loaches have a flattened body that requires fast flowing water and high levels of oxygen.

Tiger Shovelnose Catfish

Tiger Shovelnose Catfish should be kept in a large aquarium since they may reach up to four feet in length. Although the wild habitat is appropriate for fish, a small form of the fish is suitable for standard aquariums. They are named for the tiger-like stripes that appear after they are about 6 months in age.

Sturgeons

Sturgeons are prehistoric creatures that swam the waters of Earth before the dinosaurs.  They can be found in both saltwater and freshwater in North America. They look like they are five sided due to the five rows of bony plates around their body. Also, they don’t have teeth in the ventral mouth, thus barbels help them to locate food on the tank bottom.

Carps

Carps are found in North America and are usually transported to Asia and Europe and are able to survive in the most polluted of waters. Common carps use their ventral mouths to grab the food along the bottom of the tank since their teeth are situated in their throat. Common carps eat algae, insects, larvae, and plants from the bottom of the aquarium.
