Cirrhinus and Thiaminase

[Midwater]

I can get a bunch of mud carp very cheap that I could use as feeders. But I am not sure about Thiaminase.

Generally, I use tilapia, which is low, and stay clear of tinfoils, high. But what about Cirrhinus?

I see. No one knows.

You can always play it safe be using them sparingly as an addition to your feeding regimen. No need to avoid them completely, just as an occasional meal. I have a few thousand Rosy Reds (loaded with Thiaminase) in my freezer, and continue to feed them occasionally to various predatory fish, reptiles and even birds. I just make sure that they make up only a very small percentage of the diets of those critters. I give a lot away to some locals as well; one of my neighbours uses them as a treat for his chickens!
