  1. nah they ok, when you feel something wriggle under your feet in the surf, most ppl think they are flounder but more likely they are these guys. a 20cm one would do some nice fillets tho. to scare you even more, they do travel upriver and can sometimes be found in freshwater

    good article. if you can't be bothered reading it all here is the summary

    How can I avoid the thiamine deficiency syndrome?

    Prevention is the best way to “treat” the thiamine deficiency syndrome. Things to avoid include:

    1. Restrict feeding thiaminase containing fish to no more than 20% of all meals.

    2. Avoid feeding exclusively frozen bivalves or shrimps, because these potentially have very high thiaminase content.

    3. Avoid fish that was frozen for long periods (several months).

    Things to do:

    1. Keep the diet generally as varied as possible! Remember, nutritional shortcomings in one type of food will be cancelled out by the other types of food, so the more types of food, the smaller the chance of nutrient imbalances.

    2. Soak food in a vitamin product intended for pet fish prior to feeding at least once a week, more often when feeding lots of shrimps and bivalves!

    3. Get small packages of food, and use them up quickly.

    Final words

    Thiaminase-containing food will not be instantly lethal to your pets, but over the long term can result in a slow decline in health. Simple measures and a little conscientiousness when buying and preparing food is all that is needed to easily avoid Thiamine Deficiency Syndrome.
