just wondering, do fish have long memories? i mean, do they remember everything like humans do? or do they forget what happened a short while ago?

I read somewhere they suppose to have a 10 min memory
but E never forgets when I walk in room to swim to corner of tank
as I feed him there.lol
and if a stranger comes in the house he plays dead
or flares his top fin up to look big and tough.lol

like Dogs suppose to be only to see certain colours so mainly black and white

Right - there is a scientific paper that has been repeatedly redone and proven withthe following basic results

Fish have a recollective memory of 6months - ie you chase E with pink net on a certain day - he will remember what pink net is upto about 6months

As long as whatever is repeated - theyll remeber it - this is why they soon learn the procedure for feeding and cleaning out etc - so it isnt true intellignece or problem solving - but its a form of habitualisation

likewise - this is how they learn friend from foe

Cleaner Wrasse and their customers were among the test subjects - if a certain wrasse bit the other fish - the fish learn not to return to the wrasse - goldfish also have a similar learning abiluity as do most predatory fish

withthtis in mind - maybe youll now understand why your fishy friends do certain things at certain times Wink

yeah i agree they do remember things for longer than we think
mine know when its feeding time - also seem to know which day i clean tank on.

I think they do remember things for quite a while. I think people often underestimate the abilities of animals. For example I have heard it said that dogs have very poor memories, and yet if that is the case what would be the point in trying to train them - they would forget things as soon as we tell the what to do.

Mind you, now I think of it, and consider the behaviour of my dog, who has never quite mastered the 'sit, stay' mode of behaviour, perhaps they have a point!! Smile

maybe your dog is too smart and thinks sit and stay is a silly command?

My sisters dog used to look at you (when you said sit or stay) with a look of 'get lost' or 'why should I' - the idea of food soon erased that thought Very Happy (probably the problem)

its amazing how they all answer to the same geneirc name - biscuits Very Happy

Well, I keep telling myself that he must be smart - sometimes - but his previous behaviour doesn't really show that.

He was worse when he was a pup. One day I took him for a walk on the field at the back of my house. It is a huge open area with a stream running the length of one side. This day it had been raining hard and the stream was very full and flowing fast. Monty was running round the field like a thing posessed, going fulll pelt when all of a sudden the field ran out and he was in took off into space like some sort of Space Dog.

He landed in the stream belly first, and disappeared off into the distance, desperately trying to swim against the current, with me yelling at him and hoping he would make it to the bank - which he did after a while. Wringing wet and obviously grateful to hit dry land he ran at me at 100 miles and hour and jumped at me, sent me flying and then shook himself dry while standing over me!! I was not impressed.

Lets see, what else has he done...................oh yes, my friend was mowing my lawn for me with an electric lawn mower plugged into the mains electrics, Monty sees the mains cable moving, decides it looked fun and chewed it. All of a sudden there was a high pitched 'yelp', the lawn mower stopped, and Monty runs in the house and jumps on my knee - he is a Labrador sized dog remember so no little light thing. The lawn mower had to be taken to a shop for a new cable to be fitted.

I could go on, but I think you might have some idea about how clever he is Very Happy

Just to add to this, I've recently had one of my Oscars in a hospital tank being treated for internal bacteria, in that tank he soon realised food came from the left corner. He's been there about 4 weeks.

3 days ago he moved back to the grow out tank (to re-introdue him to his pal) and instantly he started begging at the right hand corner - obviously remembering where meals arrive.

Even my 'pretty but dim' rainbows remember feeding times etc.
