Thiaminase levels in shrimp,goldfish,ect...

[skynoch]

I know everyone says not to feed goldfish to our rays due to the high thiaminase levels. I was just curious on what percentage of thiaminase is in our raw tiger or white shrimp that is being fed to our rays.
Does anybody have a list of the levels found in various foods. I have seen a list of what fish and seafood contain it but nothing to give any info on the amount. Or is any level dangerous.

Thanks, it did help but what about river shrimp, red shrimp, mysis, plankton and krill?

I feed alot of tilapia and shrimp. This article says polluck does not contain thiamine. I may try it as it is cheaper?

After a recent pick up that was eating pollok I started feeding it to everyone. Very soft fish if thawed in water. Also it is like a sponge. Everyone one of my rays wil take it with no problem.

Agreed about the texture. Only thing I don't like about Pollack is that it seems very messy.

Like catfish?. I hate feeding messy fish! Will supplementing tilapia and shrimp with vitamins cure the thiamine issue?

Freeze it open in the freezer. It drys it out. Then it doesn't break up as much.

The mess was mostly from my Dats. When they inhaled it, a bunch of little pieces would always break off and float around. I still feed it occasionally (pellets are their staple) since it seems to be one of the healthier foods.
