something to read on thiaminase.
Which got it right...
Thiaminase in excessive amounts can cause slowing of growth due simply to a lack of available energy for growth.
Goldies are comparatively high in thiaminase when compared to most tropical feeders, insects/inverts and crustacea.
Goldies are also high in fats not easily metabolized, which can lead to 'Fatty Liver' disease.
All in all with all the other live feeders/foods available Goldies are a poor choice.
