I've had Harpo for a day now. He's made it to 1 day! haha
I realised that he wasn't swimming around alot and seemed abit dosey. The times he was swimming he was going crazy against the wall with really sharp movements in all directions. I think this was because he could see his own reflection or something. Since, i've put pieces of paper around the side of the tank and he is as happy as can be and is swimming round the tank really energetically. :)
Anyone else had this problem?
