My 3ft tank is here. That's roughly 153 L or just under 40.5 gallons.
But make that 30 gallons.. as it won't be completely filled with water, I think. It's 50cm (1.75 feet??) in height, which is pretty tall.. I am pretty bent on the idea of a paludarium sort of thing, growing some mini papyrus (if it only grows to about 1.5 ft..) and other emmersed plants in there to give it a pond-like feel.
For substrate height that doesn't encourage anaerobic pockets, someone on AL suggested hydroponic clay ball things.. regular substrate goes over these. I'll do some research on that, as it would solve the height issue without me attempting the inevitable doomed mess of DIY anything
I'll be posting some other people's tank pics here for inspiration. :)
Like this one:
Love those air plants! And ooh, I swear there's orchids
on that wood... I -really
- like this tank! Mine would have to be well-covered, for the strohi, but something like this doesn't need to be open-topped.
These are more shallow, water-wise, than I would want. And I'd like the emmersed plants to actually be rooted in substrate, if possible, rather than in hanging pots (or both, really.. maybe..) and the tops are bushier than I'd like.. but yeah. I just like paludariums a lot.
I need to do some research on semi-aquatic plants! Lord knows, I do not need any more aquatic ones.. Well. Maybe a couple.
And definitely on the hunt for interesting bits of wood.
Not... so much the plant choices, here, but the rocks! I would hope they were held together with a dab of water-safe glue if there's fish in there.. what an interesting arrangement, however.
I just read that dwarf papyrus can be submerged to a depth of around 20cm.. or more, for the mature plants, which is a lot more than I thought.
