Rarely available captive bred Golden Mantella youngsters.
Although they are small, they do best when provided with plenty of room. Males are territorial and often fight over potential breeding sites and feeding areas. For a group of six to nine adult frogs, a 20 gallon long aquarium that measures 30 inches long by 12 inches wide by 12 inches high (76 cm by 30 cm by 30 cm) is enough space.
Although a bioactive terrarium is often the preferred method for keeping golden mantellas, it is easier to monitor frogs in simpler setups. A substrate of pea gravel or expanded clay pellets, over which fiberglass windows screen cut to the footprint of the terrarium is set, followed by a layer of moist sphagnum moss or a soil blend works well. Leaf litter should be scattered about on top. Live plants can be planted directly in the substrate or kept in pots. In addition, shelter such as driftwood, cork bark, or coconut huts should be provided. Simpler setups involving moist paper towels or a thin layer of only moss and no plants can also work, but care should be taken to change the substrate often in these simpler housing styles.
Maintain a temperature between 68°F (20°C) and 74°F (23°C) during the day, with a drop to around 60-65°F (16-18°C) at night. Occasional days outside this range are fine, but extended periods of hot temperatures may contribute to health problems. Maintain constant high humidity by misting the terrarium with water daily. During warmer weather mist heavily and on colder days mist less, with an ambient humidity level of 70-100% usually being fine.
