My wife suggested planting something “long and grasslike” so I straightaway thought of vallis. There are several species of Vallisneria commonly available and I plumped for Vallisneria asiatica as sold by Aqua Essentials. This is the second smallest vallis (Vallisneria torta being the smallest), and is listed as growing to 30 cm with pretty corkscrew twisted leaves that add interest.
I ordered two bunches, each of which came with four individual plants ranging in size from 18 to 23 cm. These looked like they had been repacked from the original grower which I suspect was AquaFleur since the Aqua Essentials website picture is a match for the one in the AquaFleur catalog. The idea is to make a “curtain of plants” up against the left side of the aquarium and whilst this was the original purpose for the Lysimachia nummularia ‘Aurea’, the lysimachia has proved to be too floppy to hold its upright position.
Vallis is considered a very easy plant to grow in aquarium, yet also has a reputation for being sensitive to liquid carbon, so we’ll see how these do where I’m still going with 1ml/40L daily Easy Carbo. I can say that upon planting the vallis, the otto catfish were immediately interested.
