Wow, I really like this tank. I only wish that is was a little brighter in order to see the sides and front more. From what I can see the only thing I would change is the sword to the left. I'm not certain that it blends in with the rest of the scape. But looks great and healthy!
This is a really beautiful tank that is photographed really well. The street of Anubias in the midground and the way the light catches the highest most fronds of Java fern makes for a very nice effect. However, I don't feel the random stand of Rotala rotundifolia is positioned properly and seems to be detracting from the overall impression. I would remove it.
This tank would be a great home for a fish! It looks much larger than a 50g.
From what i´ve observed in my case, I think the use of the gro-lux lamps from Sylvania is helping very much. I say that because now I´m using bulbs with higher temperature colors and rotala rotundifolia now is more yellowish and greenish.
In other setups, for example, I only can pull out a incredible red from ludwigia glandulosa "perennis" using the gro-lux lamps.
