Water changes
It is very important to change the water in your Discus Aquarium Fish tank on a regular basis, in a display tank I recommend around once or twice a week and with the later for breeding tanks and anything up to once a day for growing on tanks. I like to change in between 20-40% of the water in the tank but in the fish farms in the Far East they change 100% of the water once a day in the growing on tanks with great results. The reason for this is that discus like other fish, secrete a hormone into the water that inhibits their growth. This allows the fish to stay appropriately sized for the volume of water it is contained in. It is for this reason that wild specimens and those subjected to abundant water changes grow to such large sizes. When changing the water clean the bottom of the tank and suck up all of the debris on the tank floor but try and disturb the Discus Fish as least as possible. Once they feel more secure, you can clean aggressively, but do not cause them stress by being noisy about it, just remember that sounds are amplified in water as it is a much better conductor of sound and shock.
