Check my live web cam out when it's nearly 10 o'clock in the evening, the fish start hanging around where they are going to be fed. And people say they've got a four second memory, I don't think so. Memory must come into it somewhere

Yep. I've heard that they can recognize their owner from across a room too.

I am still on the fence when it comes to the subject of Oscars recognizing faces and their owners. All the Oscars I had ever had get excited when anyone goes near the tank, I've never seen any evidence that they actually recognize individuals. I think you would have to do quite extensive tests to actually be sure they can pick people out of lineup, so to speak

yes i watched a few times now and noticed they gather in the same place ready for feeding:).

as for oscars recognising people, well my oscar comes to the tank for every one but my wife. if she goes near the tank or tries to feed him he will swim to the bottom and hide lol. she has never done anything to him so who knows why he does it

yeah I agree, fish do have memories for sure. I see this with my oscars but even more so when I was much younger and had a large Koi pond. When I approched the pond they knew it was me even thought i was well out of view. if my mum or brother went to feed them, they never surefaced. as soon as I started to walk toward the pond they came up,waiting. they also got to know what cats were harmless too. my own cat sat and watched them with a paw in the water.(he never tryed to catch them)and they would swim very close and even suck at his paw. a strange cat and you wouldnt see them. People that say they dont have memories have never spent anytime watching fish.

I second on that marcus, my oscar always wailing their tails whenever I am around but remains silent or motionless to others.
