Sand Questions

[mpmistr]

Anubias does not require substrate at all. Low light plants? Vallisneria and Water Sprite grows insanely fast and but both have a rather ineffective root system. Both will root into your substrate and take hold, but they will pull nutrients from the water column. You could also look into Java Fern, like Anubias, it can be attached to driftwood, no substrate or fertilization necessary. Froggy poop will sustain all.
