Fish: Adding Fish
There are many myths about how to add fish to an aquarium. The following method, we believe, is the correct one. Please use this procedure each time you add new fish to your Tank.
- Place the unopened bag of fish into a bucket. Carefully open the bag.
- Gently add water from your aquarium into the bag. The added water should be equivalent to the amount of water originally in the bag. The water total should equate to half from the pet shop or source of origin, and half from your tank.
- Leave your bagged fish in this new water mix for 10 minutes only.
- Using a small net, take the fish from the bag and place them into the aquarium. Don’t ever put the water from the bag in your aquarium.
The reasons for adding fish in this manner are simple:
- Water temperature has nothing to do with how to add fish to a tank. Rather, the different water conditions, such as where the fish come from and where they are going to, determines the outcome.
- The mixing of the two waters is an acclimatization period where the fish can adjust from one water type to another.
Please note: never float bagged fish upon the surface water of your aquarium. The fish will have excreted, elevating the ammonia level, and when the bagged water is warmed (by floating it in the tank) it heightens the ammonia and actually poisons your fish. This is the main cause of the disease “White Spot.”
