Hey, I set up a 1 gallon bowl of dirt capped with gravel. I put in water sprite, java fern, moss at first. Then it has become a catch all for the small odds and ends adding fissidens, rotala stem, hygrophila, and one I can't recall the name of that looks like boston ivy in miniature.
It looks good, but I had to start fertilizing and occasional excel as algae became an issue. Both this an my 10 gallon dirt tank have had major algae problems. Might be I didn't' start with the right plants, or they had too much light. So far, I'm not adept with dirt.
I tried a shrimp in the bowl but he seemed unhappily desperate to get out so I took pity on him and moved him. Now it's just plants and snails.
BTW, Go Cubbies! (Northsider by birth, in Boston for work and the Red Sox just don't have the same spirit as the Cubbies, they used to... but not since they won).
