Need to know about purple waffle, table fern, and Ficus benjamina
Are the following plants good with dart frogs? I have a 20 gallon long tank. The soil is four inches deep and is on the moist side. The plants I want to know about are: Purple Waffle plant, hardy table fern, and Ficus benjamina 'Little Gold Angel'. Will the plants get too tall or stay too wet in the soil.
