Discus fish are among the most popular types of fish to keep in the aquarium. Many hobbyists today already took them as pets as they enjoy watching these colorful fishes swim around the fish tank. However, you need to keep in mind that although these fishes are very beautiful, there is a trade off. You need to remember that taking care of discus fish is not that easy. So, here are several tips that you need to remember in order to keep your discus fish happy and healthy. For starters, you may want to keep the fish tank clean. You have to keep in mind that discus fish are quite sensitive to disease and water conditions. And, they really won t tolerate sudden and large water quality changes. You can get this ingested by your discus fish by medicating the food they eat. Feed your discus fish with medicated food every 2 days for a period of 10 days. However, if you see that your fish is no longer eating, you may need to force feed them using a syringe without the needle. Keep these things in mind and you can be sure that you will be able to treat your discus fish of any diseases that they may get. So, try to change 50 percent of the water at least once a week and make sure that whenever you feed your discus fish, you need to clean or remove uneaten fish food. When breeding is successful, the fry should be separated from the adults in order to avoid letting them get infected by parasites from the adults. You have to remember that discus fish need very specific living conditions and diets. Many fish enthusiasts even say that beginners should not attempt to take care of this kind of fish as it will just frustrate them especially if they don t know what they are doing. Discus fish are very temperamental but if you do the necessary research and apply it in taking care of the discus fish in your aquarium, you will be able to have a discus fish that will thrive in your aquarium and also grow happy and healthy. A small tank will just stunt their development and will stress them out. But also remember, if the tank is too big, the young discus fish can become overly skittish and can also stunt their growth. If you can afford to, buying two tanks is also advisable, especially if you can afford it and you want to breed your discus fish later on.
