Tips for non-aggressive community tanks
3 things to know about your community fish
- "Community fish" describes non-aggressive species that can share an aquarium peacefully
- Fish in this category include the guppy, platy, molly, dwarf gourami, tetra and others
- Community fish don’t necessarily come from the same part of the world
- Habitat: Goldfish are best housed with other fancy goldfish only
How do I set up a community fish habitat?
Prepare the aquarium at least 1 day before you add any fish.
Aquarium & stand
- The size of the aquarium will depend on how many fish you have and how big they will be as adults.
- The aquarium should be near a power source in a low-traffic area, away from direct sunlight and drafts.
- Water weighs 8 pounds per gallon. Pick a very sturdy, stable base for the aquarium before filling it.
What do I put in the aquarium?
- If you will be using an under-gravel filter, add it first. Then layer about 3 inches of gravel on the bottom of the tank (about 1½ pounds of gravel per gallon of water). Rinse the gravel before putting it in the aquarium.
- Fill the tank about halfway up with dechlorinated water and add bacteria supplements to promote biological-waste breakdown. Add a thermometer and other necessary equipment.
- Time to decorate! Add fish furniture, rocks and plants. Rinse all décor before placing it in the tank.
- Finish by filling the tank the rest of the way with dechlorinated water.
- Maintain a healthy environment for your fish by testing the water frequently and changing 10% of the water weekly. If you are unsure about the health of the water, bring a sample to PetSmart for free testing.
- Follow the manufacturer’s instructions for choosing and setting up the filter.
- An aquarium filter should be able to process all of the water in a tank 3 to 5 times an hour. For example, the filter in a 20-gallon tank would need to treat at least 60 gallons of water each hour.
Heat & light
- In order to thrive in the same tank, the community fish you choose must be suited to the same basic environment. For example, tropical fish require water temperatures ranging between 73 and 82 degrees Fahrenheit.
- Choose an aquarium heater with 5 watts of power for each gallon of water in the aquarium. A large aquarium may need a heater at each end.
- Wait 15 minutes after filling the tank before turning on the heater.
- Place the heater close enough to the filter to distribute the warmed water.
- Run the tank’s filter and hood light for 24 hours, then check the water temperature and adjust the heater if necessary.
What do community fish eat?
Feed your fish flakes or pelleted food twice daily. Use appropriately sized pellets, and only as much food as the fish can consume in 3 minutes. Supplement their diet with frozen or freeze-dried brine shrimp or tubifex worms.Shop community fish food
How can I keep my community fish healthy?
Even after they are settled in, fish can get sick. Contact a veterinarian or a PetSmart store associate if you notice any of the following signs
- Unusual swimming pattern
- Thinness or decreased appetite
- Abdominal swelling
- Inflamed or discolored skin or fins
- Fins clamped to sides of body
- Scraping body on rocks ("flashing")
PET SAFETY TIPS
- Thoroughly wash and rinse your hands before contact with your aquarium.
- Use caution when moving fish.
- Supervise children around the aquarium.
- All animals can carry viral, bacterial, fungal, and parasitic diseases that are contagious to humans. Thoroughly wash your hands with warm, soapy water after contact with any pet, its habitat, or aquarium water. Adults should assist children with hand-washing.
