Yeah agreed brilliant idea
I would love to be in a position one day to do a properly researched freshwater UK tank and get the best ornamental fish from our rivers they must exist! Other than sticklebacks I dont know where to start....

My dad had a really nice huge tank when I was little, we took a fry net to a large river and scooped up 20 or so mixed fry and put them in it, watched them grow up into rudd, roach, gudgeon, carp, barbel, bream, all sorts! Had a freshwater eel in there as well at one point, as well as some stickleback (but we couldn't get them to feed so we took them back).
I'm fairly sure it's illegal to do that though...
Oh and Roy I really like the tank, I'd love to do something like that one day. Was it hard work getting all the marine life?
