I just repaired a little 5-gallon tank...
It's too small for any fish, but I was thinking about just planting it heavily, with maybe a shrimp or thai micrro crab colony.
Most of the plants require a temp around 70-75 degrees, and the same for the shrimp/crabs.
Would I be able to get by with not using a filter or a heater?
Note, I'd have about 25 plant stems, an emersed amazon sword, and a corkscrew val or two. (would place the ones that got too big into one of my other tanks, or sell them on aquabid)
Also, I read on another site that you can use a mixture of "loamy" soil and vermiculite as a substrate, covered in a shallow layer of sand. Anyone ever tried this?
Should I just use sand, or sand/vermiculite? (the sand is "pool filter sand" so it won't compact and will allow water movement between each grain.
I'm more than willing to experiment since it's only a 5G, and easy enough to break down and start over if need be. (the plants would only be about $16 from sweet aquatics)
As far as lighting, what would you reccomend as a starting point? I'm leaning towards just placing it in window, but I could probably find a 6w CFL. (I think its the smallest you can get!)
If the consenus is that I would need a filter, it will probably be an air-driven sponge filter.
I may break down and place a single male guppy into the tank too, but I'm not sure.
Here is a list of plants that I'm considering:
Would a PH of about 6-7 be okay?
(I'm anxious to start this!)
