In the new juvenile gharial exhibit in the Chinese courtyard area at Pairi Daiza (former Chinese giant salamander exhibits, the salamanders are now in the restaurant in the Mersus Emergo reptile house ship).
I did a little research on ZTL to try to properly determine the bottom species, and I think I found both species!
The Filament barb (Dawkinsia filamentosa) and the Tambraparni barb (Dawkinsia tambraparniei). There are a lot of similar looking species in the Dawkinsia group, but both of these species are also held in Antwerp. Meaning they were probably both sent from there!
It's really no trouble! Researching things to a ridiculous extent and doing deep dives is kinda what I do!
I once copied every animal ZTL listed for Burgers' zoo and clicked every. single. link. to find which animals were BZ's rarest. So this was nothing in comparison!
