Purchasing new Discus from a local aquarium shop should be followed by certain steps to be healthily acclimated into your tank as below.

To acclimate new Discus fish from a local store, follow the below steps:

  1. Open the Discus plastic bags they came in.
  2. Put the Discus bags floating (with the Discus fish inside) in the tank’s water.
  3. Fill the same amount of the bag’s water with your aquarium water, you can do that by either using a cup or pushing the bag’s opening into the tank’s water.
  4. Leave the bags floating on the aquarium water while opened.
  5. Add to the bags a general Aid medication.
  6. Leave the bags for about 15 to 20 minutes floating.
  7. Use a fish net to grab out the Discus and drop it into the aquarium.
  8. Through the empty bags with their water away and not in the tank.
  9. Turn off the aquarium light for some while so the Discus can feel safe in the new place.
NOTE: Leaving the bags for 15 minutes on the tank’s water will ensure that the Discus acclimatizes to the aquarium water temperature, and for mixing tank water into the bags, in this case, the Discus will not be shocked to the new water parameters by eventually getting used to the new environment’s parameters, and the general aid to protect the tank from any harmful bacteria the bags would have from the source.

Note I have asked you to grab the fish using a net so you throw the bags with their water away and not added it to the tank.

NOTE: In case you have more than one Discus in your bags, do not grab them together at once in the net, instead, transfer them one by one to avoid any possible damage to the Discus.

Acclimating New Discus Fish Shipped From Overseas

You should also note that in case you purchased Discus fish from overseas, the shipment might take several days to be delivered to you, with that being said, the Discus fish will be very tired from this long trip and might take like 24 hours to acclimate the new environment and to look healthy, however, they might look not that bad.

So, in order to acclimate new Discus fishes delivered to you from overseas, follow the below steps:

  1. Prepare a separate tank for the Discus fishes as a quarantine tank.
  2. Put all the bags floating in the tank’s water for 15 to 20 min (without opening them)
  3. Prepare an empty bucket with your fishnet.
  4. Cut the top of the bags quickly and throw the bag’s content into the bucket through the fishnet.
  5. Using the net, transfer the fish into the quarantine tank.
  6. keep them in this tank for few days till you find no health issues shown.
  7. Transfer them into your tank afterward.
NOTE: In case you do not have a quarantine tank at your house, then its fine to transfer them into your tank directly, however, having a quarantine tank at your place is essential for you as an aquarist, so if in the future you have a Discus ill you should treat it separately in that tank for some days.

When you receive a Discus package, you might see the Discus fish looks like its dying, do not be afraid this is so normal, once you transfer it to your tank, turn off the light and leave it till the next day you will find them looking perfect as expected, however, you might see some dies after a couple of days and this is also normal.

Why you shouldn’t open the Discus bags directly from overseas?

The reason is that the bags have almost no oxygen inside of them due to the long transport journey, and due to that the water pH should slowly decline and this is normal and there is no issue with that as long as the toxicity of the water at this low level is very low (which is something good), however, when we open the bags, the oxygen will enter again causes the pH to rise back quickly causing the ammonia toxicity to be fatal to the Discus fishes in there.

Conclusion

Discus fish is a very sensitive fish, so adding a new Discus into your tank require you to follow certain steps in order for your new Discus to acclimate to the new environment, so be sure to keep healthy Discus by following the steps provided to avoid having health issues or in worst case scenario dead fishes.
