Thanks folks Jobysp I got him from universal waterlife ltd in widnes.
He was the only one left at the time and when I went back the next day he was still there all on his own so I just had to buy him now 'didn't I'
Well to be honest josh was the first fish I have bought from there and have had no problems touch wood, but they do have a good selection and do a loyalty card scheme, where you get a stamp for every £10.00 spent with them then when you have collected 5 stamps you get £5.00 back, not bad when you think how much we spend on our fish etc.
