Self aware tiny fish?

An study published in the prestigious Nature journal has found that the Bluestreak Cleaner Wrasse, a small fish of only around 10 centimeters has been able to identify itself in the mirror. This is a test that once distinguished great apes as having increased intelligence.
Anecdotally, six year old African children cannot pass this test, so it is kind of unique. But I have seen a lot of cats and dogs that pass this test too, so it seems like a lot of government funded research does nothing
Fish are cool though. Scuba diving won.
