Re: New Build & Springtails
Nice looking vivarium! You'll have some happy frogs once you add them. Looks like you have good lighting. The plants will grow in nicely. The only things I might add are more of personal taste. I like adding some cork bark to make a cave area for the frogs. I also am partial to adding live moss. I've had success both with the spore mixtures and with leaving dead sphagnum moss in a brightly lit area of the tank until its spores grow.
I find that springtails' population growth is proportional to the amount of food available. I imagine that there is little decaying matter in your vivarium now because of its age. You should start seeing more once you have waste and decaying leaves
