so pretty.. ram expensive kah?

hey folks!

I dont do planted tank, but erm, i would like to get advise from u guys about getting plants that are similar to anubias or maybe anubias family that are able to :
- grow their root in sands
- roots submerse in water while stem and leaf are above water
- if possible mininal sunlight required
- preferable wont grow taller than 10 inches
- effective in absorbing nitrates
- hardy
- can withstand pH level of 6 - 7.5

my purpose of the plant is to absorb nitrate as effective as possible..

Some people recommend me pandan leaf..while i am currently testing with some anubias..seems to work fine, but they tend to grow pretty tall..

Any advise and comment are much appreciated!

Cheers mate!

looks good..are they gonna grow all their way on anything they get to cling onto?

to whom that are interested to buy my xtra flourish excel...
that's the bottle which I buy just now...
I even print stickers to label the bottle so you would not mix up with others...
