This is so attractive just hanging in the garden. When the day wanes and the lights come on, it’s  spectacular !! The only problem is a big one - the lights only stay lit for an hour. I’ve moved it to different locations, same thing. Cleaned the solar pane- no improvement. The solar panel appears to be to deep in the ‘mouth’ of the fish. No matter what I do it does not get charged enough. I would buy this for all I love if it only worked. Any ideas
