Damian;
The Rotala grew out of a 22cm Ikea Rektangel vase.

It looks pretty tatty now, and needs to be rescaped, but is basically a clump pf Rotala and a carpet of Glosso. growing in Aquasoil.
For the pictures, It is a "don't steal my shot" kinda thing. Over the years I've noticed a couple of my pics used on eBay, and an occasional orchid, or aquarium plant forum "for sale" advert.
If someone says "This is an example of what you'll get" I generally don't care. But if someone implies that they will get that plant, I don't want to be a party to false advertising.
Cheers.
Jim
