Hi, thanks for the info. Do you think this is an Emerald? If you look at my avatar pic, that is the same fish. The spot marks along it back have gone. ( Maybe a stress thing ) Also his head was quite was the lighter colour. He has now, as the week passed he has relaxed and the large kind of finger print markings have gone. The body is a brown mottled trout look and his head has darkened to almost black with a purple/blue. Really there are so many variations, I wonder do I have an old age pensioner or a teenager. lol He is 10 inches long. His head would be 1 inch and 3/4 wide. and the price of £80
