No not really. It's nice for them to have a friend, but most of the time they behave more like a dog than a fish. They will wait for you to get home, watch tv, dance around in the water when they know you are about to feed them etc.
there is a series of fish you can breed to get the magic fish. The frist magic fish comes when you first get the game then breed a bunch of fish together untl you get the rest
The eggs doesn't have this fish,you need to breed it
To get the angel fish, you need to breed unicorn fish and fairy fish together
You don't need one to breed and i don't think you do to sell.
It depends on the breed, you will need to be more specific.
Because they are easy to breed. some people like the way they look. and some people need a food source for their larger meat eating fish
No. You need one of each.
Fancy goldfish need 10 gallons per fish while common and single tail goldfish need 20 gallons per fish. The fish need more space, and they need to be around 3 years old before they are old enough to breed. The fish will be around 4 to 5 inches long w/o tail when they are the right size to breed. A bowl is not the proper home for a goldfish they are too large and messy of fish to live in a bowl. Once they breed you will have around 100+ fry (baby goldfish) that will be 1,000+ gallons of water that will be needed to raise them.
Obviously you need another to breed so put up posters asking for what you need. Maybe put an add in your local paper.
There are some fish that have evolved to live in groups (shoals/schools)and so are uncomfortable by themselves. There are others that have evolved to be on their own most of the time but all fish need mates in order to breed successfully.
You will need a pair firstly. If you have a true pair and feed them well and keep their water A1 they are easy to get spawning. The next thing you need is a properly set up 50 gal tank to spawn them in. The hard thing is rearing the babies. You will also need at least 10 x 100 gallon tanks to grow out the youngsters.
You can breed sudowoodo with another sudowoodo or a ditto. To get another sudowoodo, you will need to trade for one. You can also breed a ditto with a sudowoodo to get another sudowoodo. Make sure you ask the daycare to see if your ditto gets along with the sudowoodo.
