depends what type it is
Feed your betta fish cooked & de-shelled peas for 2 days instead of his/her regular food
Feed him? if he refuses to eat them he's sick, but they can live for seeral days without food.
You will end up killing your Betta if you don't feed it properly. Canned fish for humans is no good for Bettas. The Betta will not eat it and it will poison the water.. Bettas are insectivorous fish and will eat Mosquito Larvae, Brine Shrimp etc. A Betta can live for some considerable time without food, so if you can't get to a pet shop and buy some Betta food, you can always order Betta food online and should get it within a week or so.
There is betta food on the market, and if you should purchase this food the fish is not going to gulp this down right away. Bettas do not eat like we do, they go for days without eating it is best not even to try to feed a betta every day, one way to know if a betta is hungry or other fish is too watch them in there habitat, if the betta or your other fish are around the top and very active drop some food in, if they or it is just taking life easy do not feed them or it.
fish will live 3 days without food.
It's hard to tell without a lot of details, but maybe you are feeding her too much... :( You are probably overfeeding her. Try not feeding her for a few days- but don't worry bettas can survive without food for a whole week.
Betta fish change color by there environment and the types of food that you feed it. If your Betta fish is loosing color that means that your Betta is sick.
Yes, Betta fish can jump. You can teach them to jump by placing a small amount of food on your finger and when your betta fish is ready, it will jump and take the food off your finger! :)
no they eat freeze dried blood worms,live food,or Betta food bought from a store.
NO
Provided you have followed the basic rule of "1 inch of fish needs a minimum of 1 gallon of water" (so a Betta needs at least 3 gallons of water) and the tank has a cycled filter. (to remove deadly Ammonia and Nitrite). The fish will be perfectly OK going without food for 3 days.
