Time to start an official journal on this project. I'm going to custom-build a tank to fit on the back of the desk in my music studio, and I just ordered the glass. It should be ready to construct in about a week. I've been kicking around this idea for several months and it's exciting to finally commit.
So, here's the plan.
Tank: 36"x10" x10". The water will be about 6" deep, with 2" for substrate and 2" for emergent plants. The lid will have four 2x3" holes for rice plants to grow through. This will be a walstad-style setup, with no filtration except the plants and substrate microbes. A very small powerhead will push the water around. I'm going to put a fluval aquasky light on top with a 5 on, 2 off, 5 on light cycle.
Plants:
Dwarf rice (Oryza sativa)
Paddy herb (Limnophila aromatica)
Assorted crypts (planning to try balansae, wendtii, and parva and see what does well)
Christmas moss (Vesicularia montagnei) on back wall
Arrowhead (Sagittaria latifolia) or dwarf arum (Zantedeschia aethiopica) to simulate taro, which is commonly grown in Malaysia paddies
Critters:
2 Betta imbellus
15 or 20 blue rasboras (Sundadanio axelrodi or Sundadanio goblinus, depending on whom you ask)
15 or 20 dwarf rasboras (Boraras maculatus)
6 shadow catfish (Hyalobagrus flavus) or 5 kuhli loaches. Still up in the air which.
Malaysian trumpet snails
Ramshorn snails
Lots of inverts: Scuds, water fleas, assorted worms, seed shrimp. I am going to build an invert refugium for an ongoing supply, but I am hoping to achieve something like a predator/prey balance in this tank.
Timeline
Early January: Get the tank built.
February: Add substrate, water, plants, silent cycle, build invert community. I am hoping a lot of inverts will come in on the plants. I will intentionally add others.
April or May: Add fish.
Well, that's enough for now. Stay tuned.
