This year I will be housing a control group of discus fry for the grow out contest. The purpose of this group is to provide an interesting point of comparison for participants and fans of the contest. I will also be happy to discuss any discus related subjects on this thread so if you have any questions or topics please feel free to post away. The discus in the control group will not be eligible for placement in the contest. I intend to raise them using the same basic principals that I use in growing out any discus. My primary focus is on maintaining stable conditions, keep food moving through their gut on a regular basis and controlling the water quality by changing large percentages of the water daily. My exact routine will likely change as the fish grow.
I am starting with 12 fry and will likely reduce this number as I go along so as to concentrate my efforts on the ones that are showing the best potential. To start they are being housed in a 10 gallon aquarium. The aquarium has a drip system set up that will change around 300% of the water daily. Every 1-2 days I will wipe down everything inside the aquarium with clean cloth and then drain and refill the tank. For discus fry I find it is really important to remove the biofilm that will build up on the glass and other objects in the tank on a regular basis. There is no filtration on this tank but there is very strong aeration. This is another thing that I consider a must for discus fry. Strong aeration from an air stone will help break up any oily film on the waters surface and keep the dissolved oxygen levels up. This will go a long way to keeping the discus in prime condition and avoid the problems that come with chronic low oxygen levels. There is no lighting on the tank but a light will be on in the room 24/7. There is a 50 watt heater in the tank set to maintain the temperature at 88F. I have an Eheim Automatic Twin Feeder on order that will be able to dispense Australian Freeze Dried Black Worms to the discus every 4 hours around the clock which I know is going to really boost the growth rate of these fry. I have a couple of extra feeders coming in case anyone else is interested in purchasing one. I will also give these fry the occasional treat of frozen seafood and live grindal worms. Overall with the automated water changes and automated feedings this will prove to be a fairly low maintenance discus tank.
Please feel free to ask any questions about this set up and group of discus.
Here are some photos taken the day I set up the tank, June 8th, 2015. The largest fry was exactly 1.5" total length.
