I agree with BrianNY. Low light plants. I haven't researched the biotope on the link you posted, but I suspect that some of them require high light. Looks like the tank is over 100g. About the same length as my 55 and the same height but twice the depth. That would make a great planted tank. I've been thinking my 55 isn't deep enough.
Some of the plants on the page such as the Myriophyllum elatinoides and Mayaca fluviatilis are bunching plants and pretty high maintenance. If they grow well, you are pruning, if they grow really well, the propagate, if they don't grow well, they get leggy due to cellular elongation and are pulled after a few weeks. I had some cabomba in the tank, still do, but was replacing it every couple weeks because it simply isn't getting enough light to grow well in my tank.
Notice that other tank also uses
CO2. If I remember correctly, if you go high light, you pretty much have to add
CO2 to keep everything in balance.
You know a school of angels would look nice. I saw a tank of Angels at the Columbus Zoo and Aquarium. I was happy to see that the 8 year old angels in my tank, 55g, were the same size as the angels in what looked like a 300g tank.
I should see if I can take a picture of a tank at our AA. I love the tank, it's a SA theme, but has Java moss in it? Two nearly black long veiled angels with some corries and other fish. They use a very fine gravel for the substrate and has some drift wood in it as well. Next time I go I'll try to remember to take the camera.
