You laugh instead of educating yourself on how to keep discus fish in order to achieve ones goal. Why would anyone put anything into a tank except what is absolutely necessary when every day they do water changes and clean the tank? The fish I raise are to be put into show tanks later not now. This isn't some school boy hobby here. Huge $$$$$$$$$ is involved. If my goals wasn't for breeding trying to develop a new strain just strictly for one tank in the house I'd do a planted tank kind of like this one. <img src=http://zhenuk.sc35.info/discus1/Aquadesign/3.jpg> I'll be more then happy to help you have that in your home if you want. Give you all the resource's to go do it.
