Hi PCS, here is my 280L Discus Aquarium. I have had the tank running for about 6 years, 5 years with Discus and dither fish. The largest Pigeon Blood is about 5 years old. I find that Cardinals Tetras are much better in this tank than neons, they last longer and grow a little larger. Rummy-Nose Tetras are great indicators for water quality. There is also 8 Cory-Dora's in the tank hiding away, which love sifting though the bottom of the tank. All the plants are real and this tank does not run on C02. Lighting is LED done by myself, there is approx. 50w of LED in there (I think)
