I have fed my Garter/Ribbon Goldfish for 13 years. Is Thiaminase a problem?

I would scent the pinky w/ the fish

Step 1. Drain all but a tiny bit of water from the fish bag
Step 2. Place the thawed pinking into the corner of the bag (remaining water and all the fish should be there
Step 3. Swish around (I usually do it about ten times)
Step 4. Dump all of the contents into the snake enclosure or feeding tub
Step 5. Watch as the snakes goes into "OH MY GOD FISH" mode

I've also found taking a single fish and using it to rub down the mouse excessively works very well, incase you didn't want to buy a bag of fish
