Have to say I liked them all for different reasons but I had to pick 3. It was natural, the fish all had plenty of space, but the tank didn't look remotely close to empty. I like the I'm assumeing Amano style of 5 but to me that type looks almost to perfect, I still get that squeeky new tank feel from those types of tanks. And the Cichlid tanks where all goregous fish, obviousely well cared for and stocked carefully. If I judged on fish alone I would have picked 1 for the stunning Manga, 2 for Plant selection and use, cichlids and plants are a hard combo. 4 for it's use of space, I really like the rock layout at center.
sweet tanks all
