I plan to get some for my discus tank. Only people who kept them post please, i want experience not what you read on internet sites thanks. Now, i've kept harlequins before, they nip each other, the weakest one dies first..then the next weakest and so on, now i'm odwn to 1 and he's been there for ages and i used to have 14-16.
