Who 'Has' and 'Hasn't' had success keeping a Copperband?

[rishu_pepper]

Had one for several months, always fed live blackworms and was a voracious eater. Unfortunately it upped and died one day for no apparent reason, wasn't stressed or fighting with any fish or had any signs of disease, no idea what happened. That was a sad day, it was my favourite fish. Don't have the heart to keep one again.
