Whats the issue with smelt? Is there some reason not to feed it? Got a couple pounds of lake smelt left over from the rays not liking it and planned on using it for the armatus when larger.

Alot of larger armatus have been dying here in the states over the years. Alot of the ones we know of were fed smelt. Rumor has it that some smelts contain thiaminase.

The bags I have are called lake smelt which apparently are caught out of the great lakes, a forage fish known to contain Thiaminase.

But from the following article I just read the problem isn't in eating them as part of their diet, it is in being their whole diet. So my understanding is predatory fish cannot be fed a diet heavy or exclusive of Thiaminase because it destroys or inactivates thiamine (B1) which is essential for the nervous system. Wild predaory fish for the most part keep a balanced diet which prevents them from becoming Thiamine Deficient (lacking B1)

But apparently shrimp is heavy in thiaminase and Tilapia is not. Also rosies are heavy in thiaminase so I will be converting my armatus to something else soon.



Pretty decent read about Thiaminase and Thiamine (B1):

Couple articles on great lakes forage fish and thiaminase:

No problem..
Start now working on tilipia! Lots of current help blow it around to catch their Interest.

My last armatus and my rays were fed mostly lake smelts... I have completely stoped using it.
