I just picked up a young arrowana at my lfs, he's a perfect little dude and pounds bloodworms when i put them in the tank. I'm wondering if any of the experienced owners on the site could recommend a good feeding regiment i haven't owned one for a number of years and always love to hear other opinions on raising these awesome fish.
new arrowana feeding advice please

I recommend insect feeders, good quality pellets, and chopped smelt/silversides/talapia etc.
A varied diet is always best!
I do recommend avoiding high amounts of frozen shrimp, fresh shrimp is great, but once frozen it is very high in thiamese which leads to calcium deficiencies. Also avoid mammalian meat such as beef heart, fish cannot break down these fats so they build up on the liver, the accumulative effect leads to heath issues such as liver failure.

Awesome thanks for the advice, and Im not a fan of beef hearts at all

Thiasimine does not cause calcium deficiency. The amount of thiasimine does not increase from being frozen. Unless you live on the coast all shrimp has been frozen. When you see it on ice at the grocery they thawed it out first. Just ask the guy at the counter. Although fish can't digest mammaluan meat well, the fat doesn't build up on the liver any differently than other fat. Overfeeding our fish is the primary reason they die prematurely from fatty livers. That is something most of us are guilty of.
If you believe the things you stated are true please provide the source.

DC mentioned tilapia 4days ago. He certainly wasn't referring to whole tilapia for an aro that size. You need to try it, your aro will prob try to eat it if he's hungry. Have u tried anything other than bloodworms yet?

I'd not feed my fish beef heart because I think it reduces their life span. It certainly might be healthy, but until someone publishes a study showing it has no effect, I can only use my limited common sense. Fish did not evolve with mammals as a big part of their diet, and don't live in the same temperature as carnivorous mammals live. It's logical, if in error, that fish will fail to digest the foods properly. If that's incorrect, I'd err on the side of caution.

Per this article, the problem with thiaminase is that it destroys the B1 while the fish is frozen. By the same token, while I'm not against feeding fish frozen items (like tilapia, shrimp, etc.), I think it should not form the bulk of the diet. I lean towards a plentiful amount of HQ pellets along with some live foods (e.g., worms, insects), with frozen or fresh aquatic items mixed in. A variety will probably be healthier.

I sum up that article about thiaminase by one its quotes. "there is a distinct lack of solid information"..Certain species react in one way or another when ingesting too much thiaminase. Any evidence it kills arowanas?
