Hi,

A nice, clean tank and plants looks healthy.

Any details on tank specifications (size,ligthing,substrate,plants,fish,ferts,CO2 etc) ?

It seems that your tank is the rectangular setup (same height everywhere). This kind of setup/style, dosen't give you a lot of areas of free space, so no depth...and no clear focal point too..first time see the tank..my eyes from the left to the right..no stopping..and then its over..heheheh...just my opinion ...you may want to try the concave setup, high on either side and low in the middle..

Regards
