A planted aquarium throws off humidity like a jungle. The Boston fern that loves that steam is the same plant whose wild cousins grow on riverbanks -- the line between "aquarium neighbour" and "aquatic plant" is thinner than it looks.

| Humidity lovers | Boston fern, maidenhair, fittonia, moss |

| Tank environment | evaporation raises local humidity to 60-80% |
| Shared need | stable moisture, no dry shocks |
Putting the tank to work
Set humidity-loving houseplants on a shelf above or beside a planted tank and they drink the evaporated moisture for free. A tank in a dry room becomes a microclimate -- the same stability principle GreenNest applies to a steamy bathroom (our GreenNest DIY terrarium guide), just driven by fish instead of a shower.
Why this is crossover thinking
Most keepers treat the tank as a sealed box and the ferns as separate decor. Pair them and you get a self-humidifying plant corner with zero extra equipment -- the aquarium does the work a humidifier would. See the cloudy eye early signs for the planting that drives the evaporation.
