I would have imagined that any fish that had been kept in a glass tank for a while might have got used to the idea that its reflection was visible sometimes. But I’ve not been inside a fish tank to know whether the reflections are there or not.

Now I want to be inside a large aquarium tank to see if I can see my own reflection… also because I like swimming.

If only there were some way to see what it looks like inside an aquarium without climbing in. :thinking:

You know that thing where you sit in a pool while some sort of fish nibble your dead skin away?

This is how they do it for heads.

At risk of potentially quibbling in an article that is primarily about how certain fish can tell whether or not they are badwrasse by looking in the mirror; the honestly kind of weird thing about aphantasia is how it (mostly) doesn’t interfere with task like size comparison that one might naively expect to work by generating a mental image and comparing it to the visual one.

There may well be some differences(not actually sure in which direction) that you could tease out with careful testing; but it’s not like people who can’t visualize things are incapable of telling whether they are larger or smaller than others or eyeballing whether or not a suitcase will go into the overhead compartment or the like.
