Thear care is similar with other Rhacodactylus.
The cage: - not so small - I have keep the pairs in 60*60*120(h) cm, but no problem to keep them in little bit small cage. It will be very good for geckos to put inside many branches, cork tubes and big pieces of cork near the cages's walls. Small pieces of cork bark will be goof buttom substrate.
Temperature 25-28C in the day and 18-22C at night.
Humidity: 75-90%
Food: insects, bananas, some other sweet fruits. Some specimens use the newborn mices.
Be carefull as they are very fast geckos.
The females have give born to two babies in halft year (for R.t.trachycephalus). Vocalization are typical for pregnant females before few hours to babies borning. The male can be cannibalistic. They need around 3 years before sexual maturity.
