Cool mate.. but have a read at this..

"Among the food fish families consumed by man, species that contain thiaminase include minnows, carps, herrings, anchovies, goatfishes and snappers. Many different invertebrates have also been found to contain thiaminase, including mussels, clams and shrimps/prawns such as those in the genus Penaeus, sometimes in even higher concentrations than those found in fish."
this is from the above link.. so once in a while should be ok.. your best bet is tilapia for an exclusive diet.. economical and i'm sure you can get it there..
