Many people do use moss, but it can be problematic. On the substrate, it takes away space for leaf litter, which is much more beneficial and should be maximized. Moss also might encourage keepers to keep the viv too wet/humid.
Broms are useful for thumbnails and Oophaga as tad deposition sites, but are not useful in that way for tincs.
Tijl, might larger broms (larger than Neos) be useful in larger tinc vivs simply as general plant cover?
@Socratic Monologue , well explained !
I have both big neoregelias and or vrieseas in my tank, but is is more for looks to match my other tanks in the rack system.. The tinctorius will sit in the big bromeliad arms from time to time , but is is simply for "shelter". Shelter is better created by using pods, wood, cocohuts,...* The plants are mostly for decoration and the human eye. I like using bigger leafed plants in Tinctorius tank. Like Epiprenum or philodendron. Plants with bigger leaves give the both shelter and look out spots for males.
Almost everything about tinctorius habitat and behavior is explained in this article :

As you can see in the article, they spend a lot of their life around fallen and cracked trees. That is why I change the position of the nuts, pods and big pieces of bark in the tank. This can trigger them in breeding.
*Males also tend to hide more than females. In captivity I notice the males spend a lot of time in the pods. That's why it is important to give them lots of hiding places.
