Hey britney, seen you on the leo forum. Decided to get into Phelsumas? =)
These guys are active, so give them a big enclosure, with lots of vertical space. I used to keep my grandis in a 3x3x5 foot enclosure with sansevieria, bromeliads, ferns, and pothos. Be sure to include several driftood pieces or bamboo stalks as they can get 'flap tail' when walking on glass all day.
Provide UV lighting 12-14 hours a day, with a strong basking spot (mine love heat).
Spray the tank daily to aid in shediing, and to keep humidity up. They rarely drink from water bowls.
Main diet is Crickets. I also feed the occasinal wax worms, mealworms, silkworms, lobster roaches and fruit babyfood. Always occasionaly dust the food with a supplement.
Dont handle them too much as they are skittish and have fragile skin. However, i used to let mine roam around my room for hours, and i have never seen any damage to the skin before. I also take it outside often on a sunny day to bask in some natural UV.
Theres a few caresheets on the web on these guys, you just have to do your research. Ingo and others on this forum has more experience than me, and might fill you in on some more info. Until then, www.daygecko.com has basic stuff you might want to read.
Good luck,
M.N
