    We have a goldfish. Our toddler will put her toys around the outside of the aquarium. Every few days she’ll swap them out. The fish will swim down and look at each one. They both get something out of this arrangement.

      (Sorry if you already know all this, I’m just excited about this and wanna share with people reading through comments)

      Its still unclear how much that reflects on fish broadly, and the researcher has actually expressed a belief that many animals could be much smarter than we have assumed because our experimental design was inadequate

      In their research they chose the color red for the mark on the fish (the mirror test and some other tests used for assessing animal intelligence requires a mark be put on the animal)- the researcher chose red because the parasites they have exposure to are red (clearner wrasse are fish that work in complex social groups to clean parasites off larger fish. I’m not sure if they might be impacted by red parasites themseleves or if its the color they look for when cleaning other fish, or both).

      When later tested with green they acted as if the mark wasn’t there, so the researcher feels theres a chance that tests failed to adequately take into account the way animals experience the world and may not have designed tests in line with what information would be ecologically significant to them. Had he not thought carefully about it and picked another color the test would have shown exactly what people expected of fish- that theyre not that smart

      This was a super cool video covering the progression of research https://youtu.be/s_aNH4hXz8I. For a long time his results were dismissed so he just kept writing papers and collecting more evidence

        You are delightful, and I really appreciate you, and this comment of yours. I didn’t know about this, but you’ve piqued my interest enough that I’m going to go read more about it now. It’s super cool!

        No? I think it still looks fine. I think Pixar did pretty well in choosing what types of things they could get away with animating at the time with their early movies.

          still looks decent, yeah, but modern animations just look way different. there’s something a little bit off about that maybe, though I can’t tell from a still image. that image might just be uniquely bad, i remember the movie being way more beautiful overall.

      I used to have gold barbs that would watch TV, I assume the motion of it was more interesting than the same old plants and driftwood in their tank

    Are they in a… spotlight? Do they only like the spotlight?

    I’m not a whale biologist, but maybe they want more spotlights
