Upvote the fermented fish!
It tastes way better than it smells - and the smell from a freshly opened tin is the strongest and most pungent.
In Norway we settle for a more palatable version - "rakfisk" made from freshwater fish like trout, instead of herring. It is also is fermented and smelly, but far from the same level as the Surströmming.

As a kid, I used to keep freshwater fishes like Bettas, goldfishes, tropical (Angel), tiny frog (from a tadpole), cra(w/y)fishes, etc. I probably have old photographs/photos. buried somewhere from the 1980s/80s. I used bowls, hexagon tanks (small and huge), etc.

Agreed, not a piranha, not even a characin... especially not if it was caught in the ocean (piranhas are freshwater fish)... people however, are often quick to peg just about any mean looking fish with big teeth as such. I wonder though, where it was caught, too bad there is not more information about it.

commentary and corrections:
nitrite-cancer link: Still controversial. The American Cancer Society recommends reducing consumption of nitrite-preserved foods.

10. Catfish -- http://www.cfsan.fda.gov/~frf/sea-mehg.html
average 0.049 ppm of mercury according to the FDA - not the worst, but not as good as salmon or almost any other freshwater fish.

9. Canned Soups typically have about 50% of the RDA of sodium per 120 calories, and that RDA is based on a 2000 calorie diet. I.E., to meet the sodium RDA, canned soup would have to be a tiny percentage of your overall caloric intake. MSG serves a dual function as a flavor enhancer and preservative, but it's not really bad for you in moderate quantities

8. Bacon: There's a little bit of protein and cholesterol with the fat and salt. Of course it's still bad for you.

7. Fast food burgers...

6. Twinkies have almost no vitamins, minerals, or protein... They're mostly fat, starch, and sugar.

5. Chips ... she exaggerates.

Translated lyrics from http://www.mognet.net/artisttranslation.php?id=1094&translation=english :

Fish Fight! Fish Fight! Fish Fight! Fish Fight!

I can live in a lake or wherever, I am a natural freshwater fish! I fight with my body
A Oh! A Oh! A Oh! A Oh! A Oh!

Bass fishing is a trend, carp fishing has begun and ended; children, remember this well!
A Oh! A Oh! A Oh! A Oh! A Oh!

It's alright if the cold rain gets your cheek wet, look down to the bottom and see
Dance dance dance dance with me! Let's swim!

A carp is a living thing, and you shouldn't eat it; unrefined and smelly fish! fish! fish!

You wash a crap, and then you eat it as sweetened boiled fish, and carp sushi

In times when you cry, those in the water don't understand; so cry with all your might
A Oh! A Oh! A Oh! A Oh! A Oh!

Even if the cold rain falls upon your heart, look down the bottom and see
Dance dance dance dance with me! Let's swim!

A carp is a living thing, and you shouldn't eat it; unrefined and smelly fish! fish! fish!

My brunch is young bees and earthworms; lure fishing, decoy fishing, they're uncalled for

Char, Bitterling,Surf Smelt,Mottled Shovel-Nosed Frog, Rainbow Trout, Black Bass, Millet, Snake Head Mullet, Chub, Trout
Haya, haya, haya! We are friends, the freshwater fish!

Flounder, Yellowtail Tuna, Parrot Fish, Ocean Sun Fish, Mackerel, Sea Robin, Red Snapper, Striped Jack, Alfonsino, Scorpion Fish
Eat, eat, eat! They are the major saltwater fish!

Someday I'll have a high-grade brother too: Tiger Globefish, fatty yellow-tail, it's a piece of cake! It's my turn to be scientifically dissected
The scales, the back fin, the bladder

A carp is a living thing, and you shouldn't eat it; unrefined and smelly fish! fish! fish!

You wash a crap, and then you eat it as sweetened boiled fish, and carp sushi (And pickle it!)

Someday I too will be revolving sushi; I want to revolve, I want to be seen, fish! fish! fish! (round and round)

Handrolled, battle ship rolled, winding, pinched; anything as you like it, you decide

Fish Fight! Fish Fight! Fish Fight! Fish Fight!
