Iknow goldfish have high thiamiase, and i never feed my fish these but guppies have no thiamiase am i right? and also do endlers have the same as guppies in relation to thiamiase levels?

just been offered lots of endlers at a good price and normally i feed guppies once a month or so but will get these endlers if the are the same.

thanks guys.

Here the explanation behind thiaminase and it carries a list with fish that carry it.
Hope this helps.
