Arowana feeding

[Fishman Dave]

A local LFS here in the uk seems to sell the same but frozen as a thin block, sort of defeats the purpose for me as they are dried too, must make freezing them awfully difficult. Probably hence the price of £4 for about 25 of the little sprat like buggers in a wafer. If you drop them in they too just float, so again they must need rehydrating.
Would like to find a cheap alternative in a bag like yours. All types of fish, prawns, musselmeat etc are becoming very expensive here and hard to find. Even simple whitefish that once was £4 for a 900g bag is now £10 for the same.
With a number of monsters, I’m gonna need to set up an entrance fee and charge relatives for looking round the fish house soon!
On another note, I learnt many years ago that we were safe to feed freshwater fish on marine fish and vice Verca due to the “no chance” of transmitting disease, but lots of things have changed/moved on since then, not sure it still stands.

I always felt the same way. The thing with Viktor's fish wasn't a disease transmission issue, it was something to do with nutrition itself. Can't recall if it was in a thread regarding feeding catfish; I think it was a much more general feeding plan he used for many of his large predators. It was a very interesting thread; I don't have easy access to marine fish other than for human consumption, so I lost track of that thread as it was mostly academic to me.

Local aquarium shops here sell frozen Silversides in tiny packages for feeding turtles, predatory fish, etc. At the price it goes for, when purchased a few ounces at a time...you might as well buy a boat and motor and collect the stuff yourself. Bait stores here sell frozen whole Smelt for fishing, but Smelt are a thiaminase species so again not ideal by itself as a food source. Frozen baitfish are sold cheaply, but they are heavily salted...and they are sourced by the shops mostly by just collecting the dead stock from the bottom of their bait tanks, so...

In the past I had access to easily-netted huge quantities of shiners, which I froze and stored for my own use. Not as easily done where I live now; minnows can be trapped, but that is a relatively slow and painstaking process, compared to scooping up a netful of many hundreds or even thousands. And, of course, now that I am aware of thiaminase (of which I was blissfully ignorant back in the bad old days...) I would need to check that as well.

It all circles back to the idea that these natural foods should probably be used...if at all...in smaller quantities, as part of a varied diet. If you plan on feeding your fish a diet consisting of only one or two ingredients...then one of those ingredients needs to be a properly formulated commercial feed.

It's for human consumption. I'll try to attach a picture. Lol don't rost me for the small aquarium, I have a 2000L waiting for him, he just needs to grow a bit

Those are ikan billis if I’m not wrong. My helper uses them for cooking sometimes

They look like glass minnows aka an anchovy species we have here in Florida and catch (and buy frozen) to feed our fish.

Feeding marine fish to f/w consumers has been one hypothesis of the high death rate we have experienced but it wasn't mine and it was and still is too low on the list of all possible causes so I don't worry about it. For now. Priority-wise, it would seem to me like worrying about ruining your shirt when you are being shot...
