About 30 seconds.
Ok, a couple weeks longer than that. This tank was put together 7 weeks ago, and now the tallest terrarium plants have hit the top and are growing sideways. I’m going to trim them in the next day or two and root the trimmings for another tank. This is a pretty good example of how choosing the right terrarium plants for your tank can affect the upkeep necessary.
A lot of these plants are considered common or beginners’ plants, so I’m going to address this post to newer amphibian keepers. Although I’m keeping dart frogs, these plants are suitable for many other amphibians and some reptiles as well.
If you want your tank to fill in quickly, several of the plants I put in this tank may be the right choice for you. These plants will also do well with tree frogs and ground frogs. I’ve kept several of these terrarium plants with Tomato Frogs, Big Eyed Treefrogs (a couple different Leptopelis species), Fire Bellied Toads, and a variety of others, even including Whites Tree Frogs. Whites will crush these plants, so they’re best used as a filler around branches or heavier plants, but they will recover quickly, so they can do well with the larger frogs.
The predominant plant in this tank is Tradescantia fluminensis, commonly referred to as “Wandering Jew”. It’s a very common plant for dart frog keepers, frequently found as a house plant, and considered an invasive species in many parts of the world, including the Southeastern US. As you can see from my tank, if it likes the conditions, it explodes.
Also in this tank are two small ferns (one is visible on the right side of the photo if you look closely), an unidentified Columbian Peperomia, an unidentified small Philodendron, Selaginella kraussiana, Pellionia repens, and Ficus pumila. All of these are great terrarium plants.
Here are some pictures of a few of the plants before they were put in the tank.
I always thought this philodendron would get larger as it aged, but so far this is about as big as the leaves get, making it pretty suitable for terrariums. If you have a larger tank, other more common Philodendrons will work too. I have kept some larger Philodendron species in a 55 gallon tank with Whites Tree Frogs, and it worked out pretty well.
I imagine these ferns will eventually outgrow the tank, but they grow quite a bit slower than any of the other plants in there. These were purchased at a nursery and carefully treated to remove any chemicals over a few weeks time. Plant nurseries often carry terrarium plants and may have a section dedicated to them, like the one near me has. Keep in mind that these plants may have been treated with chemicals, such as bug spray or fertilizers. Wash them carefully before exposing your frogs to them.
Pellionia repens is often called “Watermelon plant” or “Watermelon vine”, which is pretty ambiguous. Google “watermelon vine terrarium” and you’ll get a dozen different species on the first half of the first page. This is a good example of why I prefer scientific names (when I can remember them!).
Pellionia repens will take over a tank as well, just not quite as fast as Tradescantia fluminensis (Wandering Jew). This cutting was given to me by a fellow dart frog keeper. You can find vendors who will sell and ship it to you with a quick google search. A similar species, Pellionia daveauana, has been available at Home Depot in my area recently. It will also work, but be aware that it may be treated with chemicals and wash it before use.
This Peperomia was collected in Columbia and given to me at a reptile show. It has large leaves, but remains pretty leggy, so even when it takes over (which it will try to do as well), it doesn’t choke the tank up quite as bas as Tradescantia fluminensis.
Many Peperomia are commonly available. While you may not be able to find this specific type, there are hundreds of Peperomia species, and many are suitable terrarium plants.
