    1. So they don’t swim upside down, we just decided that their up isn not the normal up so we call it down

    2. Cool how their coloring also kept with the trend.. dark colored bottoms and light colored tops, basically the inverse of upright swimming fish

      Weird. Looks like a catfish variant. Seems counter to their feeding to swim upside-down, assuming they ARE a catfish breed. Maybe they evolved to skim food off the surface instead of the bottom. I got questions. . .off to google.

      EDIT: Seems like I was right on all counts.

      I had two of these in black and didnt know anything besides that they look cool.
      I had them togehter with mollys and guppys and so on in a 240 liter tank, and mysteriously fish gone missing. I didnt notice at first since the tank was pretty crowded but after a while it was obvious.

      Didnt know why until one night, the aquarium lights where already out a few hours, i saw a molly tail at a weired angle peeking behind a stone. I watched closely and saw it was half way in this mf’s mouth, who was maybe two cm bigger than the molly.

      They then got exiled into a pond of someone i know

    5. So do they actually swim upside down or is it just “it looks like it swims upside down” because we have a ‘standard image’ of what a fish looks like and this deviates from it.

      The “true” upside-down catfish (there are several catfish called this, but this is the original and the only one that swims like this all the time)
