I believe this is T. microlepis (2 spots on the dorsal fin, small scales across the lateral line), but not listed on Zootierliste. Would need a dorsal ray count to be sure.
Went to the zoo today just to check out the Archerfish feeding in the Australian Riverbank exhibit within the Amphibians and Reptiles building. It was really cool to watch the Archerfish blasting the crickets off the stump with the turtles waiting below to catch a quick snack... check it out on...
