Pop, it's of some comfort to know 'somebody' is watching you! lol
I don't know about the mirror experiment. I've often wondered about these shoaling fish. Just recently, after losing a few over time, I added 4 more Neon Tetras to the 4 I've had for a long time. The new ones are much smaller, but immediately joined with the others. How do they know what they look like? What bonds them together?
I can make the case that in groups, they 'know' each other, but when a new group instantly joins an old group and are accepted, it's an interesting mystery of sorts.
True also of varieties within species. I recently added a trio of Sunburst Platys that seem to hang together even with other Sunset Mickey Mouse Platys and a few Redwag Platys in the mix.
