i seen a advertisement for a free tank today and thought why not it would do my molly fry for the time being however when i arrived the geezer said i had to take the fish that was in it and i said ok no prob what kind were they to which he replied i dont know they are goldfish kinda things


1)the first thing is what kind of fish do i have ??? like i said they are similar to the picture above
2)one of the fish has what i can only describe as a large blue pupil what is this likley to be and how can i cure this ??? poor fish

3)what is the diet of these fish??? i did get given goldfish flakes but as a tropical fish keeper can i also feed these fish frozen brine shrimp/bloodworm as i do to my tropical fish
anyother useful info and help will be much appriciated thanks in advance joe
