I ordered some wendtii bronze from knuggs for my goldfish tank so I plan on planting some of the smaller ones in the back. I'm going to try to have a moss carpet area too, I ordered peacock moss from him. And maybe a small lotus in the corner. I have some in my ten gallon floating on their bulbs.
Yea, my petsmart has mopani wood in the reptile section, it leeches tannins like crazy in the begining but purigen will take care of that!
