Curved spines in Fry

[jimbo_natale4]

Is it genetic or is it due to handling with the net? Is it water quality issue or tank size issue? Space issue? Help I don't know I've had to cull half my July fry.

The only thing I can think of is strontium poisoning. it can cause deformed bones. diet is also another potential cause. insufficient proten can cause such problems. Insufficient food may have also played role.
