Thank you Steven, really appreciate it.

Can't update/reply sooner, something is wrong with this forum, just like 'nyawa-nyawa ikan', near to death..hahahha..

Anyway, maybe you are right, all Rotala sp. green background, will not able to create depth..perhaps combination with some taller grassy plants like Vallis should do it..I am not sure..have to try it first..thanks

Regards
