The unique characteristics and wide variety of freshwater crustaceans provide an appealing addition to your aquarium. Freshwater crustaceans come in a variety of colors and patterns, bringing the lower level of the aquarium to life.

 

Typical appearance and behavior

  • Crustaceans are characterized by their hard, jointed exoskeleton, which they molt during growth periods; they may burrow or hide during molting stages
  • Scavengers who will help keep the aquarium clean by consuming excess food
  • Some shrimp feed exclusively on algae and are great for algae control
  • Some crustacean species are known to readily breed in the aquarium
  • Many species of shrimp are highly social, living in large groups
  • Lobster and crayfish species can be territorial

Habitat

 

Habitat size

Keeping in an appropriately sized aquarium of at least 5 gallons is recommended for smaller crustaceans. A minimum of 10 gallons is recommended for larger crustacean species.

 

Building your habitat

  • Water health - Provide proper filtration to ensure optimal water quality to help maintain health. Moderate water circulation, based on species, should be provided to mimic water currents and high oxygen levels found in most freshwater crustaceans’ natural habitat. Stable water quality (pH, ammonia, nitrate, nitrite) and water temperature are critical to the health of aquatic life. If you are unsure of your water quality, bring a sample to Petco for free testing. Ensure water temperature does not fluctuate more than +/-2 degrees direction in a 24-hour period
  • Décor- Providingrocks, plants and other décor to create hiding places is beneficial

 

Feeding

 

What to feed your freshwater crustacean:

  • A well-balanced freshwater crustacean diet consists of:
  • Flakes, freeze-dried, sinking pellets and wafers or frozen food
  • Plant (algae) or animal matter

 

Things to remember when feeding

  • Feed a small amount once daily
  • Ensure food reaches the bottom of the aquarium; if unsure, drop sinking pellets into the aquarium at night; alternate protein and algae-based pellets
  • Thaw frozen food before feeding
  • Feed a variety of food to ensure complete nutrition

 

Freshwater crustacean care

  • Water care: Maintaining great water quality with regular water changes and adequate filtration is important to help keep your crustacean healthy
    • Daily: Check filter, water temperature and other equipment
    • Weekly: Test water quality at least once a week
    • Weekly to monthly: Change 10 to 25% of the total volume of water every two to four weeks, or as needed. Change filter media monthly
  • Crustaceans need calcium to grow their shells and some species prefer soft water
  • Copper-based medications can be toxic to crustaceans

Avoid overcrowded conditions; they are a major cause of stress and disease
