ok,
well I have been breeding ciliatus and auriculatus for almost 4 years now. I would say that Rhacs and Phelsuma aren't too similar in care. I keep my Phelsuma much more humid, depends on species, then Rhacs. I also keep my Phelsuma in verticaly oriented terrariums. I would not use a normal 10 gallon for Phelsuma, but thats just me. The temps are also very different, depending on the species of Phelsuma. I keep my klemmeri much warmer then my Rhacodactylus. The feeding is similar, I use clarks and day gecko diet, along with various insects. I NEVER use baby food, as it is inferior to other MRPs available for Rhacodactylus, but baby food for Phelsuma ins't as bad as it is for Rhacs. Also, UV lighting isnt required for Phelsuma, but I have had good sucsess with it, I also use it on a few of my Rhac cages as well. Phelsuma are very rewarding and great display herps, and laticuada are gorgeous!
Good luck.
I dont have any laticuada experience, so someone who does should post.
Hopefully Jeff and other Rhac/Phelsuma breeders will post soon as well.
