Doe's the hardenberg anchovy/Indian anchovy contain thiaminase?

[HAAAAAAAA]

I feed my bigger tessalata eel mackerel whole so it's easier for me to inject some vitamins in the whole fish but I can't seem to feed the whole fish to my other eel since he's smaller and upon reading the chart listed for fish with thiaminase I didn't seem to see this species of anchovy in the list so I just wanted to ask, does this species contain thiaminase?

I don't know about that species specifically, but in general, fish in the Engraulidae family do contain thiaminase. The question then is, how much, and does the fish's diet offer enough B1 to overcome this? Without actually running samples, there is no way to know that.

In general, it is always a good idea to supplement carnivorous fish with B1 and vitamin E. I use Mazuri ThaiminE paste, but that is not routinely available to home aquarists.

ThiaminE Paste Cartridge

ThiaminE Paste is a blend of vitamins for marine mammals, birds and other aquatic species whose diet consists mainly of raw fish. This supplement contains no vitamin A and should be fed with whole fish containing livers, which are a good source of vitamin A. The paste format makes it easy to mix...
