I currently only have Leucs. I've kept aurotaenia, auratus, bicolor and imitator in the past
I like this idea and I hope you continue with the build.
If this is going to be against a wall you could have a background that is a picture of the area you are trying to replicate attached to the outside of the back glass panel, like what is done with aquariums.I understand that some people think this. But I'm going for maximum realism here. You wouldn't find a palm tree within half a meter of a giant vertical wall anywhere in the area on which this is based.
I love iNaturalist for finding kayaking, fishing, hiking and foraging locations. Want to find a nice fishing/kayaking location? Center the map on your area, search for a fish or aquatic plant species and look around. Want to help a Venezuelan coworker find Asimina triloba fruit that reminds them of the Annona species that they miss from home? Show them iNaturalist and a topographical map of the hiking trails in the park that has a lot of iNaturalist data for Asimina triloba.At a first glance the Naturalist website seems great for finding plants.
