thank you for the advice 
have been asking around and am trying to get something from an established tank.
have a few fish stores to visit tomorrow as well, so can ask if they sell anything also.
i was wondering, there is a shop called cheshire-waterlife that is quite near me,
it says there that they acclimatise all the fish to the same water PH etc etc so that it is easier for a new owner,
do i want to steer clear of buying from there because their method of acclimatisation might have already stressed the fish?
or is that something most shops do just dont advertise and use as a selling point
they are an expensive place to buy fish, however when i was last there, the tanks looked rather grubby IMO so i think im best steering clear. but other than that, there's only really pets at home (i dont drive you see, so any fish shop needs to be within walking distance of a bus. lol) i think id rather go to pets at home where the tanks are clean if you know what i mean. also had healthy goldfish from there so...
