Whoops! I misread this week's as fish ONLY from Cypriniformes, Perciformes, or Cichliformes...

Here's some more aquarium fish:
🐟 Tetras are Characiformes
🐟 Corydoras catfish are Siluriformes
🐟 Livebearers are Cyprinodontiformes
🐟 Gourami are Anabantiformes https://t.co/zawHFW2IO4

Interesting find while ct scanning. This Clarias stappersii had eaten a frog, which, in turn, had a fish in its gut - a cypriniform by the looks of the pharyngeal jaw.

Another forgotten specimen of mine. Pimephales vigilax, the bullhead minnow.
