A "string of dolphins" (Senecio peregrinus) is a popular succulent plant with leaves that resemble leaping dolphins. It can be a lovely addition to a bioactive terrarium, but you need to take some care to ensure that you are not placing it in an enclosure with animals that eat plants as it is mildly toxic. It also makes a wonderful hanging house plant. 

Plant type: Succulent, low maintenance
 
Originates: Native to arid reigons of Southern Africa.
 
Recommended habitat and enclosure: String of Dolphins will do well in a Grasslands BioActive enclosure. It can also be placed in a Desert BioActive enclosure, but on the cooler side. This plant is mildly toxic and should not be placed in an enclosure with animals that eat plants. 
 
Toxicity: This plant is mildly toxic and should not be planted in an enclosure with animals that might eat this plant such as a Bearded Dragon or Uromax. If your animal does not eat plants it will do just fine with this plant planted in its enclosure.
 
Mature size:  6” tall and with vines growing up to 3ft long.
 
How to keep this plant pruned: Trim this plant by pinching back the strings.
 
Sun Exposure: This plant requires plenty of bright light to thrive. A UVB, or bright LED will do the job. It does not want to be placed in the shade of taller plants in a BioActive terrarium. As a houseplant bright indirect sunlight is recommeded. Direct sunlight can scorch the leaves.
 
Humidity: String of dolphins is adapted to drier conditions, so maintain low to moderate humidity levels inside the terrarium.
