I have mentioned Hatchets in the past and almost got a group of them instead of the pencils the other day. But yes, I agree. Something big enough to do a decent sized school of maybe two pencil species. Something like the corys on the bottom. Very heavy planting (easier to hit that in a 20 than a 55!
). A tank that size would be relatively cheap to set up too.
Definitely a 20 long. I have a 20g normal (I guess the "high") which is 24 inches in length. It was my spare plant tank, then it got taken over by Farlowella, now it is the spare plant tank again [moved the Far back to the 10, the three of them are now about 1.5 inches and doing well, though I am still not sure they are eating prepared foods; I think they are coming along fine though]. I was looking for another tank this past week, and spotted the 20 long at 30 inches. Odd I had never noticed them before; anyway, i was thinking it would be nice for quiet stream fish like those we are discussing here. i nearly bought it, but I do need a bit more room. I have an ideal spot for a 30-inch tank, and I'd like to put the SE Asian pond fish (in the 33g) in a 30-inch, so a 29g seems best. I'm in the midst of major tank shuffles.
Anyway, in a 20L you could have two groups of pencils, a group of 12+ hatchets, and a group of corys--the pygmy or dwarf species would be ideal, and the Farlowella. Lots of plants like swords, the pygmy chain sword from me, the dwarf sword, a couple Echinodorus bleherae (these will work in small tanks for many months). Some floaters like Frogbit (mine is reproducing again like crazy, after nearly losing all of it
) or Pennywort--I can give you all of what I've mentioned. A single strip T8 daylight tube. And sand--not one to suggest sand often, but I am becoming convinced it is better for the pygmy/dwarf species. Regular corys are fine on small gravel, mine have been for more than 20 years; but the dwarfs may not be. Sponge filter is more than adequate. As you say, not a big expense.
