Fortunately, there are natural solutions to this issue, and the Theodoxus snail is one of your strongest allies in this fight.

Theodoxus snails are tiny, inconspicuous animals that greatly contribute to aquarium cleanliness. These snails have a unique talent for devouring algae, particularly the tenacious and difficult-to-remove varieties that can cause problems for your tank. Theodoxus snails can help you cut back on the use of harsh chemicals and manual cleaning in your aquarium.

Theodoxus snails are especially attractive because they are very low maintenance. They require very little upkeep and grow well in a range of water conditions. They are therefore a fantastic option for both inexperienced and seasoned aquarium keepers. They not only aid in the management of algae but also give your tank some interesting movement and activity.

All things considered, Theodoxus snails are a great addition to any aquarium that has an algae problem. They provide a low-maintenance, all-natural solution to maintaining the best possible appearance for your tank. Therefore, think about using these snails as a practical and environmentally friendly solution if you’re having trouble with algae.

Habitat

Russia, Belarus, Poland, Ukraine, and Hungary are home to small snails. The Scandinavian and Baltic nations also contain them. They inhabit the water-soaked tree branches, aquatic plant stems, and stones found in rivers and lakes. They consume the detritus and algae from them. Theodoxus are visible when strolling close to the water because they frequently crawl out onto the land.

The Black, Azov, and Baltic Seas are home to a few species. According to scientists, theodoxus first thrived in salty seawater, but later on, some species were compelled to relocate to freshwater environments, where they are still thriving today.

Description of theodoxus

Gastropoda (class: Gastropoda)

Neritidae is the family (Neretids)

Theodoxus is the genus (Theodoxus).

Theodoxus is a stunning snail that can grow up to 10 mm in size in a hemispherical shell. Height of shell: 4.5–6.5 mm. The mollusk’s mouth is semicircular and has an upper edge that is slightly raised, and its shell has thick walls.

The mollusk’s habitat determines the color of its shell. It is typically olive, brown, and black in color. On the shell, white dots or zigzag lines are easily noticeable. There are also creatures that are only one color. The mollusk’s inner surface is bluish on its outer lip.

The presence of a unique lid on the rear of the leg is a characteristic shared by members of the genus Theodoxus. Lives of snails exceed three years.

Types of Theodoxus:

  • Theodoxus fluviatilis (pictured left). Snails of this species live in Russia, Europe, and Scandinavia. The shell color is brown, purple, or bluish with white dots.
  • Theodoxus anatolicus (right). Live in Turkey, Datca Peninsula. The shell color is black.

  • Theodoxus transversalis (left) is a small mollusc with a shell from gray to yellow-brown. There is no pattern on the shell.
  • Theodoxus danubialis (right). The shell of the mollusc is white with dark zigzags. Maximum size is 1.5 cm.

  • Theodoxus euxinus or Black Sea (Theodoxus euxinus, left) – snails with a light-colored shell with a pattern of specks and thin lines. Found in Romania, Ukraine and Greece.
  • Theodoxus pallasi (right). Representatives of this species live in salt water. Found in the Black, Azov and Aral Seas. Adults grow up to 7-9 mm. The shell is grayish-yellow, and dark dots and zigzags are visible on it.

  • Theodoxus astrachanicus (Theodoxus astrachanicus) is found in the rivers of the Azov Sea basin, the Dniester. The shell is yellowish in color with clear dark zigzags.
  • And other species and subspecies: Theodoxus altenai, anatolicus, danasteri, meridionalis, nucleolus, sarmaticus, varius, velascoi, velox, vondeli.

Keeping conditions

A novice can maintain theodoxus as well. They can comfortably swim in water that is between 19 and 29 degrees. Their sole source of food is the soft plaque and algae that grow on stones, aquarium glass, snags, and occasionally plants. They are always at work. The mollusks do not harm plants when they feed. Such diligent workers maintain a tidy and well-groomed aquarium.

The majority of Theodoxus species prefer hard water that contains enough calcium. The mollusks’ shell softens and starts to crumble in soft water. Limestone stones are added to the aquarium to make the water harder. 25–30% of the aquarium’s water is replaced with fresh once a week.

It is advised to keep them in groups of no more than six. They won’t be noticeable if you purchase them in smaller quantities. And that quantity of mollusks will suffice for reproduction. They are both hermaphrodites and heterosexual. Everything is based on the species.

Every snail will find its designated spot in the aquarium and keep it free of fouling and plaque. It can only be forced to relocate to a different glass or stone surface by a scarcity of food.
