i agree with Harlequinswell to a degree, but 90% of the times its genetic. fry from poor breeding stock with a dodgy gene.
My fry are usually born with a normal body but seem to grow up in her tank with deformed spines if i keep any of them which i sometimes do they grow up with normal spines even if they are from the same batch.
if your fish grow with normal spines and are from the same batch.
90% of the time bent spines is down to unfavourable conditions
