I have a planted community tank. Started cycling in early October. It was very well cycled and has remained in perfect condition since. I added fish beginning in early December. Every single fish has lived -- other than my Harlequin Rasboras. I buy them, and then they die off one by one. Then I buy more, and they die. Everyone else lives just fine. I am giving up on them and not buying anymore because apparently it is bad luck for Harlequins to be owned by me! Anyone else ever have problems like this with their Harlequins? I thought they were supposed to be super hardy but they are the only fish I can't get to live.
