This definitely.It looks like a Chalceus probably the yellow fin (Chalceus erythrurus) judging by the yellow color on the pelvic fins.
Great looking Crocs they have there. They seem to be a very happy couple. Usually not very common to find this specie on display, they're often over shadowed by other species such as the Nile croc., saltwater croc., and freshwater gharial croc. Personally I like the gharial the most, it's almost strictly a fish eater.These guys were in an exhibit with two enormous crocodiles, some Pacu, and some piranha, there were some other fish as well but not sure what they were.
