You won't find much info that is not written in German. For some reason the germans discovered how popular these unique lizards can be.
My experience is with Cten similis (13 years), palearis (12 years), and pectinata (1 1/2 years.
The only generalizations I feel qualified to state are that they like high basking zones (130 F on the basking surface), they don't seem to eat greens for me until they are about 9 months to a year old, and that it's probably best to keep them as undisturbed as possible until they are 9 months to a year old before starting taming. My juvvie similis (who inhabits a glass enclosure on an end table - I get a lot of observation time and he does not feel the need to hide from me, like eating/drinking at night.) gobbles down two zoophobas and then goes straight to the basking spot and actually nestles his stomach flat and wide on the glass, getting the most out of his available heat.
I suspect this guy could use warmer basking surfaces, but higher temps than I already have worry me. Does anyone have a Cten who likes 140 F?
They are relatively strong by then, but taming younger ones seems to me to put more negative than positive into their lives.
I had one C. quinqueceterina (spelling) but the God-cursed thermostat failed in the always-on mode. If only I had noticed it sooner
It was terrible to find him dead in his convulsed position. He was a grumpy, stressed WC from Honduras. i was really looking forward to bringing him out of his change-related stress.
I wish there were more US interest in this species and the many Ctens that are out there. Then we could have CB specimens.
I may try mating C similis. I wouldn't make any money at it, but at least my lizards could reduce the supply of imported WC's. Maybe some on this list are already doing that.
