it is always good to get some kind of filter for your fish, but natural ponds dont' always need one. the filters will keep out some bad bacteria though, and keep your fish healthy longer, and allow you to actually see them. goldfish are very hardy and can withstand quite a bit.
you get someone to help you set up your bowl
Yes, every fish tank should have a filter, but depending on the kind of fish it can be exempt. If not an air bubbler is a good idea. The filter cleans the tank, along with putting oxygen in the water, and the air bubbler also puts necessary oxygen into the water.
a week minimum to make sure the good bacteria builds up and doesnt kill the fish when you put it in a week minimum to make sure the good bacteria builds up and doesnt kill the fish when you put it in
once every three weeks
No fish is best for a bowl, buy at-least a one gallon tank with filter, and you will clean it once every 2 to 4 weeks, a bowl will have to be cleaned every week. Also, your fish can swim better with more room, become less bored, and will be happier. If this is above your budget, fish is not for you.
No, a fish bowl is not an appropriate environment for keeping molly fish as they require a larger tank with good filtration and water quality. Molly fish need space to swim and thrive, so a fish bowl would not provide enough room for them to be happy and healthy. It is recommended to keep molly fish in a tank that is at least 10 gallons in size.
It may be possible to keep 4 small fish in a one gallon fish bowl, depending on the type, size and needs of the fish you choose. It will also depend on whether or not the fish bowl has a filter, and if your fish can live without a heater. For example, because they do not get large, 4 white cloud minnows can be kept in a one gallon bowl with a filter and they do not require a heater. You can also keep a male beta or Siamese fighting fish with a few white cloud minnows; or 2 small goldfish which can grow too large or the bowl.
If you mean a bowl like a glass bowl the size of your head that you keep as a centerpiece, no. Well, you can, maybe, while they're babies, if you have a filter, aerator, and don't mind your fish dying in infancy. The only fish that can really be kept in bowls are bettas, and even then it's a good idea to have a filter and heater. Koi were developed to have a broad colourful back so that they look good when viewed from above. They are POND DWELLERS and grow to over 2feet long. To put one in a fish tank would be CRUEL!! To put one in a Bowl would be TORTURE!!!
Platys can sometimes be kept in a bowl, if the bowl is big enough and in a warm enough area. Generally, though, fish bowls should be banned and not used.
A fish bowl for homeowners fish collection comes in various sizes and shapes depending on the type of fish and the recommendation of the pet store. A pet store is a good place to purchase a fish bowl, and also Walmart and Target sells fish bowls.
The price of a small fish bowl is about $24.99! A small fish bowl with nothing in it that holds a gallon of water, costs about $6-$10. You can get them at PetSmart or Walmart. Betta fish don't need a filter but other fish do. So, that will add on to the price of the bowl. Most people like to put something in the bowl, again, that will cost you extra. So, it really depends on how much you want or need in the bowl.
You suck it out with a straw. or just do what Nemo did.
