Rutilus rutilus fillets for cichlids?

[Aw3s0m3]

Also even if the fish does naturally feed on some thiaminase containing foods in the wild, they also consume a variety of other foods so the thiaminase isn't a big concern.

To the op, I'd say go for it but just make sure to offer other foods as well. Maybe feed the fillets once a week and the other stuff the other days

My point was that if you're feeding thiaminase containing fish to fish that are adapted to feed upon them, then its fine. One must consider the diet of the predator before having an aneurism about whether or not you can feed it a thiaminase containing prey item.

And MOST tropical predators (in the hobby anyway) don't feed on thiamine containing fish. South American and African fish, which we all know comprise the bulk of tropical aquarium fish, have cichlids and characins as primary forage fish. Neither of which [normally, I have to caveat that because I can't guarantee that ALL, don't] contain thiaminase.

May I see the sources of characins and cichlids that do not contain thiaminase?

Next time I get on a computer (I do field work now), I'll dig something up for you. I don't see why you can't hit up Google for yourself, however.

Believe me, I did but I do not find any sources that cichlids or characins have thiaminase or not.

Does 24hours in the freezer kill all parasites, and things that could be dangerous to the synodontis cats, and frontosa burundi? Dont know what the temperature is in my freezer, but I can find out tomorrow.

The fillets have to be solid frozen and I prefer leave them frozen for a week before use.

Ok. How about Carassius carassius fillets?
I'll probaly just cut the fish into little pieces, no matter if its Rutilus rutilus or Carassius carassius.

It doesn't matter what kind of fish, as long as they are frozen before use.

I was thinking if they would be more unhealthy than Rutilus rutilus.

Why should it be? They are both cyprinids.
