Black water is just tannin-stained water. IAL and driftwood release these into the tank. It's not necessary for a soft water fish tank; it's a preference for some people. Stocking a 10 gal depends on your water parameters. If you have hard water you could go with a few guppies. If you have soft water you could do some small tetra or rasbora.
