Hi I just started my bio active for my 2 aft's. How does it look? Its a 20 gallon terrarium. How often do i have to water the plants? I have a creeping fig which is doing really well, Black rabbitfoots fern which is a bit droopy but doing ok, and a Rosso which isn't looking to good. The leaves look like its getting too much water but the soil over there is pretty dry.
