Do NOT feed Goldfish. A Must read for fish-eating snake keepers!

[mor]

I am a bit confused to tell you frankly
But the post is very informative ..

My situation is this , I own a female corn snake , she eat defrost mice i store and give her once a week
My problem is that I usually buy a stock of those (say 10 or so) once those are finished I need to drive a bit far to buy another stock for the future
As local pet stores in my area do not hold small mice or rodents fit for my snake size (only big grown ones which are way to big)

Has it happened I was searching for a comb for my dog and was in such a store that did not hold rodents of any sort fit for my snake , so I generally asked a girl there which was very nice if they have mice or rodunts and she said they do not hold them , but... guppies (fish) can do fine for my sort of snake...so I bought one (the price is equal to the price I buy small rodents ) and took it home.

I then tried to give it to the snake in a small flat bowl but she (the snake) did not seem to understand it was food...so I took it out...and she smelled it but did not eat it
So..I took it back to the snake water dish , and left it there, when I came back the fish was gone , I am quite certian she ate it as it was shown on her and the fish was gone..

That led me to think ... why not breed guppies ? and be done with the endless and useless runs to the pet store?
But I did see that guppies contain "presumed to be low thiaminase content." so they do? or not?
I saw this at those searches:
http://forum.practicalfishkeeping.co...p/t-89249.html
And in here it says: "Bacteria producing Thiaminase have been found in Guppies - Poecilia reticulata."
If you search this Url for key word:'Guppies' : http://www.theaquariumwiki.com/Thiaminase
And this one said it is in small doses: http://www.gartersnake.info/articles...thiaminase.php
so searching on and on...my question is:

Is it safe to give my corn snake > Guppies (fish) for the long run ?
Can you or any one let me know?
Would appreciate a direct feedback with an educated and studied answer..
thx
