Thanks all for the information. I do have some wood and will also hunt for some of those plants tonight. I'm really keen to try some pots so I might be able to set it up so the pots are hidden by the wood. In a rare burst of fish-keeping, the family have said my plants are letting the side down and need fixing
I looked at silk plants and decided I just don't like them (maybe they look better in water).
One problem I do have is I get a very small amount of green algae on the glass but get what looks like beard algae on the plants. It's not too severe but hoping to get plants that resist that while I get my lighting, ferts and liquid CO2 in balance?
