should arowana be fed mice

  • We are currently upgrading MFK. thanks! -neo
On fish lifespan, Redshark's clown loaches aren't the only very long-living fish. I know of at least 2 pictus catfish in existence that are 22 years old as of 2022: https://www.monsterfishkeepers.com/forums/threads/pictus-catfish-lifespan.744287/

Completely agreed with RD and esoxlucius. There is no reason to assume your fish will live a short time if they are taken care of well, so don't feed them bad food.

Truth bomb? LOL Nice to see you back, Egon Egon

I posted the following recently, pretty much a repost that I have been posting for many years now. This is the real truth bomb, most folks simply don't have a necropsy performed when their pet fish dies, so they are never the wiser as to what killed their pet fish.

I agree with everything you said. My point is at the hobby level most fish don’t live long enough to get “fatty liver disease”. I would say more fish die every year from divorce related anger issues or children over feeding…
I feed my dogs bacon sometimes…
If your having beers showing off your fish with your buddies. Drop a mouse in there. It’s okay to be a cave man once in a while.
 
Generally speaking, my experience is that many folks feed these types of foods in the misguided belief that they are giving their fish a big boost in protein, when in fact the vast majority of these whole foods are listed on a dry matter basis. Which means the main component, water, a non-nutrient, has been removed.

When one is evaluating foods, and nutrient levels vs quantity etc, frozen foods typically consist of 70%-90% water, which is a non-nutrient. Ounce for ounce they cannot be easily compared with dry foods. Dry foods typically consist of 5% water. The same would apply to all forms of raw, whole foods, including pinky mice.

As an example......

A typical analysis of freeze dried bloodworms.

Guaranteed Analysis
Min. Crude Protein - 55%
Min. Crude Fat - 3%
Max. Crude Fiber - 5%
Max. Moisture - 5%

A typical analysis of frozen bloodworms. (from the same manufacturer as above)

Guaranteed Analysis
Min. Crude Protein - 6.3%
Min. Crude Fat - 0.8%
Max. Crude Fiber - 0.3%
Max. Moisture - 91.2%

So fresh bloodworms are only 0.8% fat, and even freeze-dried are still only 3%.

I would wager...don't really care enough to do the research to find out :)...that pinky mice are astronomically higher than that.

I'm all google-eyed after trying to interpret all that data. :)

Are they saying that, on a dry-matter basis, a newborn deer fawn is about 6% fat (apparently based on a sample size of one)...while an adult is over 40%? I must be reading that wrong; otherwise, it's pretty hard to swallow. And a juvenile mouse is 30%?

Unless fat loses essentially no mass when going from fresh to dried...how can this be?

Not being argumentative here, just...oh, let's say...critically cynical.
 
I can't vouch for the accuracy of those tables, I should have prefaced my comment with that. My focus over the years has typically been with aquatic life forms, not mammals. Something seems amiss with the DM formula, I have cut up enough deer/moose/elk etc to know that an adult whitetail is not typically going to consist of 40% crude fat. At least not this far North, not even in early fall. lol

The exception that proves the rule? As I stated earlier, there are videos showing arowanas with suction cups stuck in their mouths, gullets, etc.

So what? It's a big world, anything you can think of has probably happened sometime, somewhere. Now that everybody has a cell phone camera and instant access to the internet, isolated instances like this are entertaining flukes, nothing more.
