Tips for the purchase

For the beginning Discus owner the purchase of the first fish is a decisive moment. Before buying your first Diskus, you should shop around at different Discus breeders and/or dealers. To begin with, I recommend Diskus of at least 8 -10 cm. in body size. Which type of Discus you decide on depends on your taste and the size of your budget. Heckel-Discus and wild-caught Discus should only be considered when you have more experience with the breed.
Dealers or breeders usually sell small Discus of 3 to 5 cm. in body size cheaply. For the beginner, acclimatizing and raising these small fish is difficult, and they often die. Rather than try to save a little money and likely ruin a good hobby before it even gets going, you would be much better off spending some more money and buying Discus of at least 8 - 10 cm. in body size. Your chances of success will be far greater.
You should choose Discus which are lively, curious, eat all offered food and are free from deformations.
Red Spotted Green Discus

I bought my first Discus from a breeder located approximately an hour and a half away. The fish were large, between 10 and 12 cm. They were packed in pairs, each pair in a 5 litre container. They survived the trip well. I transferred them to my aquarium properly (as described below), but what a shock! All the Discus became completely dark and lay gasping on the bottom. My wife and I sat in front of the aquarium expecting them to die. However, within half an hour, 7 of the 8 Discus became brighter again, resumed normal swimming, and congregated in a corner of the aquarium. One Discus was left on the bottom. After a while, one of the other Discus swam down and began nudging the one on the bottom, trying to get it to swim. It didn't take long before that Discus began swimming as well and joined the school in the corner. A little later, they slowly began to explore the aquarium. Within 14 days, a couple of the Discus had mated and laid a bunch of eggs on a root.


Before transferring the fish to the aquarium, use a hose with a clamp to drip aquarium water into the transport container. This process should take approximately one hour. Once this process is complete, use a net to move the fish to the aquarium. The transfer container water is not used. The older the fish are or the greater the difference in water properties, the longer the transferring phase should take. Smaller fish should be raised in an empty and plant-free tank of appropriate size.


Before adding new fish to an existing aquarium environment, they should first be quarantined for 4 to 6 weeks. Keep the new fish in a separate tank, feed a variety of food and observe their behavior and excrement. If no disease signs are apparent after this time, place one or two of the new fish in with the old ones. If you see no disease characteristics after 14 days, then transfer the rest of the fish. If a disease does occur, you must carefully check all the conditions, research Discus literature and seek the advice of a Discus breeder before adding medicine.
