Interesting. Someone I know in Europe was at one time having trouble with
bent spines in almost all of his fish. It turned out that the culprit was a
plastic tub used for maturing water (for water changing purposes). If I
remember correctly, the problem was put down to phenols leaching from the
plastic into the water.
