Fish and carpet pythons

[kazz]

So this is my experience.
I googled and find out carpets stolen fish from an aquarium.
I was feeding my python with fish about 4 month.
As far as my python don't eat rats or piece of chicken I was sewing a small quail and it works. The same trick ppl do when try feed carpets with rats or Cobras with rats.
My python was in shed every 2-3 weeks.
Several month ago I stopped fish diet bc of thiaminase.

Today I searched on site thiaminase table and didn't find.
Please tell me does this fish has thiaminase or not ?
Unfortunately I don't know what is a fish i English but I know in Latin Gobiidae.
Thanks.
