How we quarantine our
newly arrived Discus

On a regular basis we receive a large number of Discus fish from our supplier in Asia. When these fish arrive they have went through the mill. They will have travelled for at least 36 hours. During this time the temperature in their bags will have dropped to around 20c-22c, their stress levels are high, their immune & hormone systems are in over drive, the O2 levels in their bag could have significantly dropped.

During this time the discus are susceptible to infection from any opportunistic pathogen.


Preparing our quarantine tanks

At RT Discus We have a separate fish house specifically built for quarantine purposes. Prior to the fish arriving all our tanks are sterilised using Milton sterilising fluid. All equipment that will be used such as nets, heaters, airline and air stones are also sterilised.

Prior to entering or exiting the quarantine fish house we wash our hands and arms and apply surgical hand cleaner usually alcohol based. None of the nets or equipment are taken out the quarantine fish house and none brought in. The tank temperatures are set to between 24c & 26c. We also use mature cycled biological sponges in each tank.


Adding the fish to the tanks

Once the fish arrive we remove the water from the bag and place the fish directly into the aquarium and discard the bag. Once all the fish are in the tanks we add acriflavin. This helps reduce any external pathogens. The fish we get are from various sources so there may be a possibility of various pathogens in the bags.

We give the fish time to settle in the tanks to try and build their immune system back up. After around 1 week the fish have usually settled in, however this can take up to 2 weeks. Our QT tanks are 250 litres and we have a constant heated HMA water change system that we use after the fish have been in the tanks for around 1/2 week. This changes around 3 times the water volume in 24 hours thus keeping the water very fresh.

After around 3 to 4 weeks the Discus have recovered from their long journey and their immune system is usually back to normal. We then do 2 things. 1 Add a mature sponge filter from our existing system to the tanks and 2 add a sacrificial lamb to the tanks. The sacrificial lamb is a fish from our existing stock. This exposes the new fish to any pathogens from our existing filtration system and fish stock. If there are any problems they will usually manifest themselves in 2 to 3 days.

We keep the fish together for another 2 weeks then the fish can be mixed with our existing stock.
