There are not many differences that separate koi from goldfish. To name one of the few, koi generally grow to be much bigger than goldfish. koi also can live about 3 times as long as the maximum lifespan of a goldfish.
Bettas are shortlived fish lasting on average around 3 to 4 years. Goldfish commonly live for over 20 years or so. In order for any fish to live a 'normal' lifespan the basic rules of fishkeeping need to be observed. Those rules are. :- 1 inch of fish needs at least 1 gallon of water. Every tank must have a permanently running 'cycled' filter. :- Every tank must have at least 50% of its water replaced every week..
Most 'normal fish tanks' have filters/heaters. Bettas do not require filters/heater (though they are very helpful to have around). Betta tanks are usually smaller and do not come with the filteration systems.
I would say Bettas are more fun! They tend to remember their owner's face and are full of personality. I have 5 of them and they're all so different from each other. Bettas are easier because in all honesty, Goldfish need a big tank and are often mistreated and put in bowls when they need 20 gallons per fish at the very least. Bettas need at the very least a 2.5 gallon tank (though I prefer a 5 gallon tank) that is filtered and heated to 78-80! That's much smaller than what a goldfish needs!
goldfish are a lot more friendly but very dirty. goldfish require a filter where as bettas don't.
YES! Betta fish are very aggresive. If you put another fish tank in front of the tank holding the betta fish, the betta will flare. So i wouldn't try putting the betta in the goldfish tank.
betas are cooler because if you have two they'll fight
there is no difference DAAA!
Betta fish are best as a solitary fish and are not compatible with goldfish.
No.
goldfish. Definatly goldfish. Or betta
They are Both fish
Betta's or Goldfish.
NO
Betta fish are very aggressive. They pick at their scales and then they're gone!
yes because once i got a betta fish and i put in a tank with a gold fish the first day the betta killed the goldfish so i boult a nother goldfish it did not kill the goldfish because i put them in sepret tanks so that's what you guys should do it because i did it try it people your goldfish will not dy. my goldfish was a fin-nipper that's why it killed it because the goldfish ripped a fin off of the betta so do not put betta fish with goldfish because you never no if the goldfish is a betta.
Some are Betta's and Goldfish
The best pet fish for kids to get is a Betta. You might think oh lets go get a goldfish! But really most of the goldfishes at stores are babies and need A LOT of growing space also a Betta lives longer. Also Betta's are easier to take care of!
Betta, Goldfish, Minno
No, it is impossible. Goldfish are coldwater and have different spawning techniques than bettas.
