Actually most of my tanks remind me of little protected alien worlds. This one is a bit stranger than the others...
This corner bowfront started out as a typical "nature aquarium" setup, and was later changed to a rockscape.
Recently I had to move this tank. To prevent damage, I removed most of the water, disconnected CO2 and heater, and it stood in a corner for many weeks, just lit by a 15W T8 bulb. Plants didn't grow much, but the tank had an amazing clarity to it.
With the lowered water level some of the plants that grew on rocks turned emersed. Initially, the leaves of Java Ferns and Anubias dried out a bit. Some didn't recover, but others started to look better.
This was when I realized it would be nice to observe how our plants fare outside of their usual element.
So I redirected the outflow of my mighty AC30 to overflow the "main rock". This isn't entirely beautiful, I just haven't found a nicer looking outlet yet.
From there, I started to throw some aquatic plants into that area. You can see the Ceratopteris fern which I knew would do well in air. New Windelov leaves shooting out everywhere. There is some Marsilea that seems to be a bit angry about the missing nutritious substrate, but otherwise looks not bad.
Anubias does great, you can see the older leaves (spot alga) as well as newer ones. Lindernia, Pearlweed, Pellia, mosses... there is much more... this is actually fun. Let me know what you think.
