First you won t need to take them for walks, you don t have to give them baths, they don t demand much attention, and you don t really have to clean up after them after every while. Yes they still need some looking after but not as much as compared to our canine and feline friends. This doesn t mean though that once you have your tank, filled it up with water, and purchased your feed then your all done. You can use a water heater in your tank to keep the water temperature stable and you should also invest in a water thermometer in order for you to constantly monitor the temperature. The environment in the aquarium should mimic the natural habitat of the discus fish. You should put in logs, rocks, plants and other spots where the discus fish can hide in or shelter in. This is to prevent them from getting lonely and also prevent them from getting aggressive against their own kind. Discus fish are shy types of fishes. This is why you also need to put some ornaments and plants inside the aquarium. These things will serve as a place to hide for your discus fish. Also, you have to remember that discus fish are quite sensitive to noise. If you want to add other species of fish in the discus fish aquarium, make sure that you try adding catfish, plecs, small tetras, and other gently and slow moving fish from South America. Just make sure that the discus fish are the largest fish in the tank. When it comes to their food, discus fish can be fed with aquarium foods. Before, because of its limited supply, only a selected few would be able to get their hands on a discus fish, let alone a handful of them, luckily today, many are now able to get their hands on them, and if you re one of those lucky persons, then you should know how to provide them a good environment so that they can leave healthy and stress free. When you have finally established your discus fish breeding tank, transfer some of the water from your original tank, this will prevent your discus fish from experiencing stress in being exposed to a new tank. Don t put any gravel or sand inside your tank, this will make it easier for you to clean your tank from leftover food.
