How to introduce new fish into an aquarium safely?
With a new aquarium under your control, you’ll take the first step of an adventure of fish life. Nothing gets you more excited in fish ownership than adding new fish to your aquarium, but some planning and care can help your new tenant settle in as smoothly as possible. Proper introduction of new fish will lower stress, reduce aggression, reduce chance of diseases, and allows for the aquarium ecosystem to thrive. This article has the bare basic fundamentals of how to safely add fish to your aquarium depending circumstances.
Know Your Shopping Ecosystem
Before making any purchases for fish for your new aquarium, learn about your shopping ecosystem. Your spoiled fish, plants, and the rest of the environment will all factor into how introducing new tenants will go.
- Fish Compatibility: Make sure the new fish species will be compatible with your existing fish in lots of different perspectives, such as behavior, size, and diet- research your two species which helps avoid problems like aggression and stress.
- Tank Size: You would think you would know the size of your tank and how many fish are in it, but don’t be fooled! Due to the excess number of fish in a stocked tank can lead to cope with stress and water chemistry quality declines disproportionately.
- Water Parameter: You should test the pH, temperature, and ammonia levels of your aquarium. New fish should enter into stable parameters.
Choosing Fish
Choosing wisely will give the two of you an even more mutually gratifying journey. The fish you choose before you actually add them to your aquarium think about the following:
- Species: Select fish that species have been documented co-inhabit and get along with your existing tenants.
- Size and Age: New fish should ideally be the same size as your existing fish so bullying will be lessen.
- Health: Buy fish that look healthy. Always buy fish (hopefully) from trusted sources with healthy animals. When purchasing fish from the fish store, you want to select fish that have shiny eyes, bright color, and are active.
Getting New Fish Acclimated
Acclimation is the process that lets your new fish acclimate to your aquarium water. There are two general methods of acclimation.
- Drip-acclimation method. This is the best method for more sensitive fish. Steps: Take your fish in a small container with store water. Make a siphon in your tank with the airline tubing and let your water drip in your container at a rate of somewhere between 2 – 4 drips a minute. After 1 hour there should be somewhere close to double in your container. Use a fish net to carefully transfer the fish to the tank—don’t add any of the store water to your tank.
- Float method. This is for hearty fish. Steps: Open the bag with your fish, float it on the water surface of your aquarium for 15 – 20 minutes. This will help equalize temperature. After 15 – 20 minutes, open your bag slowly and add a little of the tank water (1 cup every 5 minutes or so) for 30 minutes. Use a fish net to remove and place the fish in tank.
Observing New Fish
After you have added the new fish to your aquarium, it is time to observe them. You will need to keep an eye on them after you attach the new fish, here are some tips on observing:
- Look for Signs that there is Aggression: Keep an eye on their relationship with the other fish. Pecking and chasing in fish is expected, but aggression that becomes excessive may indicate a problem initially.
- Check Feeding: Is the new fish eating? If the fish is hiding and not eating, it may have a level of stress.
- Check Health: Look for signs of illness such as gasping for air, swimming awkwardly, colored spots on the fish, or loss of appetite.
Adjusting Tank / Diving Conditions
After getting new fish, you may need to make tank adjustments to meet their environment:
- Water Quality: Regularly test water quality and make partial water changes to maintain proper environment conditions.
- Temperature: stabilize tank temperature, select one suitable for all of your species. When fish feel secure, that is often a priority to socialize. Providing many hiding spots, use plants, rocks, and decorations to create hiding places.
Common Errors
When adding new fish, be aware of potential errors:
- Rushing: Each individual fish takes time to acclimate, and it is one of the few times to acclime the fish in this manner. Rushing fish acclimation can cause stress, and potentially introduce disease.
- Compatibility: Researching compatibility (on line or in books) is not enough, entirely.
- Overstocking: Introduce too many fish too fast and potentially overwhelm the biological filter.
Conclusion
Evaluating when and how to add fish and other aquatic life in your aquarium is sometimes more art than science, but takes patience, research, and attention to detail. When adding fish consider the ecology of your aquarium, let fish acclimate properly to their new home, monitor health closely, and you will be able to enjoy a successful aquarium. Healthier aquariums are happier aquariums and your new fish can provide enjoyment and entertainment for years to come.
FAQs
- How long should I wait to add new fish? When you set up your tank, generally wait at least 1 week to add new fish. This gives time for tank to establish and stabilize.
- Can I add new fish to my tank all at once? Sometimes you can if you have acclimated them to your tank. Most times, its better to add gradually to not overwhelm the biological filter and to minimize stress.
- What do I do if my new fish are not eating? If fish don’t eat, always check the water parameters, and compatibility with your current fish. Fish that may need time to adjust to their new environment.
- How can I tell if my fish are stressed? Your fish may do any or combination of the following; hiding, swimming erratically, not eating and/or aggressive behavior. Monitor your fish closely especially when introducing new ones.
