Had this 29 gal tank for about a year now and have rescaped it before but I still feel it's empty. I added some Seachem Black Sand over some old gravel I had before and planted 3 Amazon Swords and several Anubis Dwarfs. Any ideas of plants I should add to the background, mid-ground, and forground?
We sell mixed bags of plants that contain Bacopawater wisteriaAnacharis and Java Moss once u reach 50 post you can PM me for details but I think any of those would make a nice addition to your already good looking tank!
Pygmy Chain Sword is a low, carpeting type of plant that does better in sand. Groupings of that might work well in your tank.
Some moss, like Java Moss or Christmas Moss, could be attached to the rocks to soften them a bit, and also could be placed on the wood. I think some moss might actually draw a little more attention to the hardscape. I like to provide at least one cave-type hiding place for fish, and if you do so you can also attach moss to that so the cave looks more natural.
For the middle area of the tank, Pennywort has some rounded leaves that would contrast well with the leaf shapes you already have. Some Crypt wendtii bronze would provide a nice contrasting color, too.
Taller bunches of plants in the back would add a lot. Ludwigia, Wisteria, Cabomba, or Anacharis would all be good options. Anacharis does best in cooler water, though.
Floating plants will block some light, but if you are okay with that some Water Sprite or Amazon Frogbit would likely be appreciated by your livebearers and may up the number of surviving fry.
The Amazon Sword gets quite large. Removing larger leaves by pinching them off at the base of the plant will help to keep it at a more manageable size.
Are the anubias planted directly in the substrate? It's difficult to tell looking at the picture, but if they are I'd suggest moving them since the rhizome will rot if it's not exposed. Most people either tie or glue them to wood or rocks.
Other than that, I agree with Akeath about getting plants with contrasting colors or leaf shape.
