If you could choose from all the freshwater fishes that exists on earth what would be the one that you would pick?

As a fairly new aquarium keeper I would have to agree with Rotem...Betta. However, as they are loners then my second choice are platies.

As to eating I will paraphase a nice ole gentleman and say "I don eat nuthin what come outta da wadda"

Definitely Walleye. They are delicious! Lighly battered and fried, or broiled with lemon and butter. You can't get better.

ouch... that is almost impossible to answer, although I could make a list of candidates.. I wish i knew all freshwater fishes, but pike and eel would certainly feature as would stickleback. But if we allow eel and stickleback on the list, then that opens it up to my absolute favourite fish, American Shad (Alosa sapidissima). Not strictly speaking a freshwater fish (and nor are eel and stickleback fully)but for part of its lifecycle freshwater is an absolute requirement. As they are about to return here I will write an article about them soon.

in brief though, it belongs to the Atlantic Shad family and was absent in the Pacific Ocean until in the late 1800's they were transplanted to the West Coast and highly unusually have been phenomenally successful in establishig themselves without affecting "native" fish in any significant manner..although there are some grumblings from the salmon lobby but then in my view that has more to do with finding a scapegoat for their decline here other than fishing rather than anything else. The story, lifecycle and continued success of this fish on the West Coast and in the Pacific is an absolutely fascinating one, and I will go into some of that in at least one of my future hubs.

as for eating (previous poster), I haven't got a freshwater favourite, having discovered sablefish (or black cod as we call it here locally), smoked and then quickly heated back up in a wok for seconds.. pure heaven. Nothing comes even close.

Are we talking to eat or to keep as a pet?

To eat, I would say Largemouth Bass. Take a clean filet, add salt and pepper, a spoonful of butter and cut up veggies-like potatos and carrots and green peppers.Wrap it in tinfoil and bake it. You can also double wrap it and throw it in the coals of your campfire. The veggies get soft and the fish is moist and flakey-delicious!

To keep as a pet, I guess a goldfish. They are easy to care for and the flaked food is inexpensive. They come in solid orange or spotted and can be mesmerizing and relaxing to watch.

that is almost impossible to answer but in my opinion betta and cichlids are fun to keep and breed, most cichlids are hardy species with unique behavior they come in many shapes, size and colors.

In nature, this specie's males have shorter

fins that those we usually see in shops,these are called by the Thai"Plakad" (meaning- "Fighter"), and are used in Thailand for show-fights (just like roosters). Although their fins are short, they are still bigger than those of females.

By looking at all the colors, patterns and tail and fin forms, it is easy to see why this fish is probably one of the most known and popular freshwater fishes.

It would have to be discus for me! Nothing more colorful and "majestic" in the freshwater fish category as far as I'm concerned. They're not as difficult as one might think to keep and even breed! I've currently got 24 spread out across 6 tanks. One display tank and 5 rack/breeding tanks. Are you asking because you're trying to figure out what to keep?

I already have chosen.The answer is Oscar Fish,because they wont to communicate with people.They are clever and funny,they live long enouph to be your friend!
