What do you feed? That is a fish was was fed seafood containing thiamine only. If you have a diversified menu with lots of thiamine free foods, then some thiamine is fine, but you don’t want it to be only thiamine containing food. A varied diet is the key. I believe that thiamine is found mostly in saltwater fish, I’m not so sure about muscles. There are freshwater muscles aNd clams, I had clams in my front ditch until the drought dried it up. Unfortunately In Maryland you cannot harvest freshwater mollusks, although there is a grey area concerning ditch cleaning on your own property.
Why mussel should not be feed to Congo spotted puffer?

That is a really good book, and I trust the information contained. There is a species that is known as the freshwater snook, maybe that’s it. Now I have to find the “freshwater snook”.
Thiamine is good, vitamin B1.
Thiaminase is broadly anti-thiamine. It exists in both salt water and fresh water fish. Some sea fish like cod and freshwater fish like tilapia are low.
I’m not surprised I mixed that up at all. Sounds like a me thing to do! Thank you for straightening me out, I need it sometimes!
So it looks like the general consensus is it’s okay, just as long as there’s non thiaminaise food items included.
The fella that wrote the chapter on foods and nutrition is or was a biologist with the forestry service. He was researching fish nutrition to try to reduce the mortality of new born fry for hatcheries. The fish pictured was the result of an experiment. I kinda trust the guy.

A new update on my puffer fishes. I tried starving them for two days and then I fed them only mussels , I mean without the shells. They ate them and I kept an eye on them for about an hour. As I saw they became uncomfortable and suddenly I saw two of them started returning the mussels from their stomach. I thought they are regurgitating but then I noticed all of the chewed mussels where thrown at the gravel. Their texture of skin the black spots became very visible as a sign of stress, and I didn’t feed them for a day and then I restarted feeding them earthworms and they got back to normal.
Maybe you have found the real reason, that was not expressed in the article. Nothing to do with Thiaminase. Puffers just can't stand mussels.
Maybe we just overfeed in aquaria vs nature and effects are seen much sooner? Just thinking out loud. I know I’m guilty of over feeding my puff.
It’s easy to do isn’t it? My suvattii, mr. Murder lips, will voraciously attack and eat until he’s at full inflation I think.
I’m not so sure the answer is the volume of food, it’s the quality and diversity a wild animal would get vs a captive fish. We typically only offer a few meal options where the wild fish could have dozens. So the concern would then be more to the fact that the nutritional value of the few food items be as healthy for the fish as possible. A food item in their wild environment could contain something like thiaminase but due to the many other options available it’s effect is minimal. In a captive environment it makes a big difference when there’s only 3-4 different foods available.
Now that we’ve talked about this a bit…..
Does anyone really know what foods we feed our fish are thiaminase free?

From https://www.practicalfishkeeping.co...d-to-know-about-predator-fish-and-thiaminase/
“There are really only three groups of foods dangerously rich in thiaminase: mussels, crustaceans, and cyprinid fishes. Mussels are popular fresh or frozen foods because they’re cheap and readily available. Crustaceans are many and varied, but we’re concerned with prawns and shrimps widely used as fresh or frozen foods.”
soak shrimp and mussel in vitachem? I do it just for extra supplementation. Im lucky my puff like northfin carnivore. I feed apple snailsand crays.
