Is that black substrate "pasir malang"?

I hope you have clear idea of what kind of substrate you are using.

Pasir malang or volcanic sand particle might originate from any volcanic region, and I found out the hard way that some are not suitable at all for planted aquaria (seriously disasterous result). Not trying to scare you, because some have had good luck with the stuff.

Lets see.... some low growing crypts would do nice in the place of the anubias, surrounding that wood. Want to create wilder look? then try saggitaria subulata.
