I've kept them,
Triblinotus gracilis are a very secretive, timid lizard which thrive on lots of hiding places, high humidity, cooler temps and lots of peace and quiet.
I found they did best in groups of 1.2 per enclosure. Some people claim the males will fight, others disagree. I found this to be true in my case. 40 gallon aquariums per group.
If you never see them, that means they are doing well. If you see one hanging out in the open during the day, that's cause for alarm.
They'll eat any appropriate sized insect, larvae, arthropod, or slugs and earthworms.
It is important to de-worm immediately with panacur and flagyl...I lost part of a group a while back from adding a fresh wild caught female(mental lapse)
I'm looking to start again with this species very soon, so if you're interested in more info, I'll be more than happy to help you out... PM or e-mail
