Just join. reading lots of good info. Have a 65gal and a 45gal tank. Going to buy a 75 gallon to house the Discus when they get bigger. Both tanks are freshwater. One tank has a bunch of parrot and african cichlids and the other tank is all discus. First time trying to raise discus. Bought a bunch of baby discus from a breeder. It has been 3 weeks and they are doing great. The Discus love beef hearts. Changing 15 gallons of water daily during the week and 75% water change during the weekend in the Discus tank.
