I noticed this green gecko of unknown species on one of the walls in the tropenhalle, sadly I was not able to get a photo of the back because of the angle. But this should be either Koch's day gecko (Phelsuma kochi) or Greater Madagascar day gecko
(Phelsuma grandis).
This species is relatively new at the park and arrived in 2021, they are kept in a pretty large group free living in the tropenhalle, and in a pair in the vogelhaus.
