Your best bet would be to separate them. They may also just be playing with each other.
in a goldfish the world
There are many different types of goldfish. The Comet and the Common goldfish are often the ones most seen. Black Moor, Bubble Eye, Butterfly Tail, Celestial Eye, Fantail, Lionchu, Lionhead, Oranda are some other commonly known goldfish.
No you should not treat an infected goldfish with healthy ones. The infected fish should be separated until it is healthy again and the remaining fish should be checked regally. Any medication you give an infected fish can harm any healthy fish.
It is generally not safe to put small goldfish with big ones in the same tank because the big ones may bully or even eat the smaller ones. It is recommended to keep goldfish of similar sizes together to ensure their safety and well-being.
goldfish
Goldfish are very gentle and low mantinance pets. They get along with each other fine and are usually not the fish that will fight. (This does make them an easy target, only place goldfish with goldfish) There is a large variety of goldfish to choose from-fancy, black colored ones, large eyed ones. However, the "fancier" the fish, the more the life span decreases and mantinance increases. To some it all up, goldfish are excellent first time pets and are great for someone of any age!
You give them other eggs and hide the ones she eats
Your goldfish will eat a lot more. You would see lots of small white eggs sticking to the aquarium walls and fixtures. The ones that survive hatch into tiny frys. Eggs should be removed as soon as possible because the parent goldfish usually eat them up.
Not normally, because the bigger fish would try to eat the litte ones. The Big Fish will think that they are food.
It depends on what kind of aquarium you have. For a tropical aquarium, to start out you should get guppies, or something else hardy that you can find out from someone else. For a Coldwater aquarium, you should start out with regular goldfish. I know it's tempting to get the fancy ones, but for a while, just stick with the common ones. For a Marine aquarium, start out with damselfish. Some other good fish for a tropical aquarium, get most kinds of tetras, Rosy barbs (unless you don't want them to breed), or Cherry Barbs. Other good Coldwater species, weather loach, Shubunkins, and some other kinds of fancy goldfish. For other Marine fish, there's Damsels, and common clownfish.
yes mine has ate goldfish almost his whole life now hes up to 20 every two weeks he also eats fish food but if he doesnt get goldfish he will not eat fish food until he gets his goldfish and the books say its ok
It is possible! Sometimes the bigger goldfish of the tank gets kind of bossy and starts to think he is the "boss of the tank" and harrass the poor little ones around. This might result in your otheer goldfish being a bit quiet, or hiding behind ornaments more. It is never good to have a bully goldfish. However, bully goldfish don't always happen.
