Once you bring the fish home, you must pay extra attention when you put the fish in the aquarium. As with transportation, various measures must be taken to ensure that the fish are exposed to minimal stress.
This is a term for adding fish, which means that the temperature in the fish bag is the same as the water in the aquarium, and part of the water in the two is mixed together. Because fish cannot maintain a constant temperature themselves, they are regulated by the temperature of the surrounding water. At the same time, if the chemicals in the water are different, the fish may be stressed and may even die as a result.
How Many Fish Can Be Added at One Time?
At any time, the fewer fish you add to the aquarium at one time, the better because the bacteria in the filter need time to grow to catch up with a load of newly added fish. Do not add more than 6 fish at a time.
Additives to relieve stress can be used to transport fish. Although not necessary, some liquid products claim to relieve stress during transportation. They can be added to the bag when packing the fish in the fish shop, or added to the aquarium when the fish is returned home.
What Is the Fish Bag Floating Method?
- Turn off the Light
If your fish is taken home safely, then the first step is to turn off the lights of the aquarium (the fish was originally in a brown paper bag or polystyrene insulation box, in a dark environment, if it is suddenly exposed under the bright light of the aquarium, it is just like the state you encounter when you suddenly turn on the light at midnight. Put the fish into the unfamiliar water environment of a new aquarium, and the stress level of the fish will rise rapidly). Open the top of the bag or box, and give the fish a few minutes to adapt to the dark to weak indoor light.
- Balance the Water Temperature
Next, you need to balance the water temperature. The most common method is to float the unopened fish bag on the surface of the aquarium. If you need to float several bags, you may need to remove some water to contain the water in the fish bags. A fish bag of average size takes about 20 minutes to balance the water temperature inside and outside the bag.
- Untie the rubber band or cut the knot to open the bag.
Add a glass of water from the aquarium to the bag and leave. Repeat this process every few minutes for the next 20 minutes, until most of the water in the bag is from the aquarium. The final result is that the fish swim in water with the same temperature and the same hydration composition as in the aquarium.
- Fish out the Fish
Use a small fishing net to fish out the fish one by one from the floating bag, and put them into the aquarium one by one.
- Pour out the Water
Pour out the water in the fish bag because it will contain the ammonia produced by the fish during transportation.
- Observe the Fish
Observe the fish in the dark to ensure that they swim normally and are not attacked by the fish which are already in the aquarium. If they are attacked, and they are not in good condition, use a fishing net to fish them out. When you have any spare aquariums, isolate them in another aquarium or put them in the plastic bag they were originally transported and tell the aquarium Shop immediately, your aquarium may have fish that cannot coexist harmoniously, and then you need to take them back to the place where you originally bought them immediately. If the fish just hides behind the aquarium, don’t worry, this is a normal behavior of the fish in an unfamiliar environment. You just need to observe if the fish is still hiding there after a few days.
- Constantly Check on The Fish
After the new fish has adapted to the new aquarium for 1 hour, turn on the light and check once every hour for the following day.
What is the Drip Method?
Put the fish bag upright in an empty bucket, and then use an air pipe to slowly drip the water from the main aquarium into the opened fish bag. This method is particularly effective for sensitive species and is widely used when placing marine fish and invertebrates.
