Plants for filterless nano tank?
My husband bought me a mini tank and I'd like to try out a 'proper' aquascape in it so I need some small plants that will work. No fish or anything just plants. Now here is the catch, I want to put it on the windowsill and it will have no filter or water circulation, no added CO2 and only natural light. The window faces South but is shaded for most of the day so there is only a little direct sun. I know this is challenging and I could improve my options with a light etc but I'd like to give it a go.
I already grow aquarium plants in jars on the windowsill. Algae can be a problem but usually I can find a balance. Some plants like vals thrive, others don't like it at all. I like the look of a jar squashed full of Vals but I'm looking for some smaller plants that will do well like this. So far I have found Micro Sword (Lilaeopsis brasiliensis) seems to quite like it. Any other suggestions?
