rainbow needs HELP

[Mr Algae]

can anybody HELP? one of my 3 rainbows has a serious eye problem. it looks like it has a film over one eye( it looks like it is blind) the gold around the black iris seemed to be all at the top of the eye. it has also gone into hidding behind a log when it is normaly very lively. no other marking that i can see at present. have checked all water stats and they are OK. havnt done anything strange or added anything new. please help.

it sounds like it could have been bullied, if not then it could be a bacterial attack.
if you have a spare tank i would seperate it from the other two, just in case it was bullied. try doing a water change and add some anti- bacterial cure in as a safe guard.
