Fish Food - Thiamine/ Thiaminase

[LBDave]

Great thread I read recently has some good info on feeders and nutrition. Had me reading up.
The Piranha Nutrition Thread
Also had me looking for Thiamine (B1) containing foods and good warning to me regarding freeze dried minnows/ thiaminase. Not sure the freeze dried process neutralizes this but have read that cooking does. So need to temper feeding these things (even though I stuff sticks in).
In any event I searched for large cichlid food (for the oscars and bass) containing thiamine. Didn't find much. I'm gonna try the jumbo sticks from Tetra. Good time to try some new stuff anyway as I'm running low on krill.
Seems the thiaminase problem is already impacting natural waters as well as aquariums.
Anyway, check out the old thread. Good stuff. Feel free to weigh in on the subject (knowledge best, opinions...eeh).

Potential thiaminase issues can easily be resolved by simply pre-soaking the frozen food in a product that contains B1, such as Boyd Vitachem, and/or feeding a quality pellet a few times a week. (or pellet stuffing frozen food)

RD,
Great news as I do soak the minnow with Boyd. Thanks!
Just read a review on the tetra site. Had me rolling . Reviewer hated the stuff because they have to clean their tank!
"I can't even give this product any stars. Since feeding this food 2 months ago I have had to clean my tank 3 times in the last 2 months and I am working on my forth. "

 

[RD.]

The horror, having to actually clean ones tank!

Just checking... You are sure VitaChem has B1?

It certainly did when I last used it. This from a past discussion on liquid vitamins, where I posted a break down of Vitachem.

It depends on what you are attempting to use it for.

What does the label on your container state? It's certainly possible that their formula has changed, I haven't used it in several years.

I saw a retailer indicating it does have B1. I have reached out to Boyd on this.

Ok, sounds good. Sometimes online vendors use old outdated information on their sites, so anything is possible.
