Striped mackerel with mouth wide open.

This fish seems to have gill rakers, which are structures used a little bit like the baleen of the baleen whales. They swim around with their mouths open, and water goes into their mouth and out their gills. The plankton in the water goes into their mouth, but is caught on the rakers and funneled down the throat rather than going out the gills. It’s kind of like if you attached a mesh funnel around your face and ran around catching flies with it, except that the funnel is also your lungs.

It looks really silly when an entire school of them does this at once. 

“Don’t play koi with me,” I say as I’m followed around the edge of the pond by fish with gaping mouths waiting for edible proof of friendship.

Banggai cardinalfish have paternal care. This dad will hatch and brood his young in his mouth until they are ready to swim out. You can see the little guys hanging out in his mouth.

These guys were the first saltwater fish to be bred in captivity specifically because they do this. Most saltwater fish spend their baby days as tiny, fragile, planktonic fry, and many fish need specific cues to breed. Banggais will happily breed whenever you keep them in good conditions, and the fry emerge from the dad’s mouth as miniature versions of the adults. It’s adorable.

my friends do not care BUT the Airbnb I’m staying at has an aquarium with two male blue gouramis and a handful of red and black wagtail platys

I thought the fish had a parasite… does it?

no that’s its sword

Those are its fins! Gouramis have two long, thin, pointy fins, which are often used like whiskers, reaching out like you see to tap at objects. Other fish have the same fins, but fin-shaped instead of poking-shape.

Multiple gouramis shouldn’t really be in the same tank, though, they’re territorial. Also that plant in the background is lucky bamboo. It’s not fully aquatic, so it eventually suffocates and dies if its leaves aren’t out of the water.
