#82: 340L Aquatic Garden Diamond Dragon's-head

Heather Gladney Sacramento, United States


This aquarium looks like a Southeast Asian stream that's well on its way to being overgrown with plants. There's a pleasing quality to the chaos and thickness of the plants and the fish are perfectly chosen. However it's TOO full and lacks any noticable aquascaping intent.

There should be an open space in the middle. It looks too disordered.

This shape tank as you have found is hard to light well. I also suspect that your plants would do better with a more reliable CO2 supply. Some of your plants seem to be struggling and as a result you are running into algae problems. Look at some of the other low-light tanks in this contest. You can have a lovely tank and still stick to plants that can actually thrive in your set-up!
