Thank you for the comment stepheus
The cabomba its not supposed to be that high for a nice shot, but I'm a bit lazy with the camera .

By the time I was watting for it to grow to divide it a litle more. But it's quite a challenge to keep it in the right size and bushy

.
Now, and not for the first time, I'm having a lot of issues with this plant and I did'nt found the cause yet. It grows ok, than suddenly looses the new leaves, they get white and die in a few days, the rest of the plant stays ok.
Some rotala I think I will put in the right side in place of the nesaea. this one I think with it's big leaves don't look so good. Has you said, bigger plants in the back, make all the aquascape look smaller.
