I'm new on having aquarium. I have a 130litre aq. since Christmas this year and I have 4 Scalares, 5 "redeye" and 2 "scrubbers"(eating "mud" at the bottom") I also got about 4 green plants and a couple of red plants. The fish seems well, but the glass, plant and the sand gets green and muddy very fast. The water itself looks transparent and clear. After I clean the glass(window) everything turn green after only a few days. The plants also get a layer of green coats, and when a new bright green leaf is growing up, it turn into dark green and often die (getting brown and transparent) fast. Some of my friends that had aquarium before tells me that I put too much food in the water, but I can't beleive so. I give the fish very little food one time each day. Sometimes so little that I'm afride that the fish want to "jump on eating me" when I open up the top. (I give them "ThetraMin" food.
