Yes, fish in an aquarium typically need a filter to survive because it helps to keep the water clean and maintain a healthy environment for the fish to live in.
To have one fancy goldfish you need to start off with at least a 20 gallon aquarium kit. This kit will come with a filter, filter media, the tank, and likely some decor. You also need to buy a bottle of water conditioner, and some fish food so you can begin cycle your aquarium to prepare it for the fish.
It is important for a fish aquarium owner to purchase a ph probe for their tank. It helps measure the pH levels in the water. Certain types of fish will only survive in water with a certain pH level and one would need to know what their tank pH level is for their fish to survive.
Simple answer is they can but it's not wise nor smart to do it. There are so many rapid ways of maturing/recycling your filter and aquarium that there should never be any need to put fish in an unprepared aquarium.
Technically, most fish can survive without pumps and air fulters in a large outdoor pond with a large surface area for ixygen to enter the water and plants to clean the water. However, if keeping them as pets you should always provide pumps and filters, ir they will live very short lives. Otherwise it would be similar to keeping a human in a dark crate with little oxygen and no waste disposal. do not belive that betta fish can live in these terrible conditions, as it is unfair to them
No you cannot do that. There are special minerals in the salt water that the fish need to survive. Even though there may be some fish that can be in both types in water. Like a dolphin. If you do want a salt water fish you could buy sea salt and add it to your aquarium.
An aquarium, if you want plants, depending on the type you may need substrate, a filter, sand or gravel about 1 pound per gallon, a light between 5000K and 6500K (it does not have to say aquarium), water purifier, water, fish food, a power strip that has at least 4 outlets, an aquarium heater if you are going to have tropical fish. and about 30 minutes to put everything together and add water
In the aquarium were water, weed, sunfish, snails, and a neon fish.
They live in water--as they're a type of fish--so they need as much water as an aquarium or an ocean can hold. The type of water for them is sea salt water, not fresh water.
A betta does not breathe air all the time, it is a fish with gills that lives in water, and it certainly looks like a fish. However, they do need to have an air space at the top of an aquarium and can survive in a wet tissue. They are fascinating fish, but they are definitely fish.
Yes, aquarium snails do need air to survive. They breathe oxygen from the water through their gills, but they also require access to the surface of the water to breathe air.
You should have either a bubble wand, or an air stone in a fish tank as this adds more oxygen to the water; this should not be confused with adding a filter to a tank, as that is a separate, but also a needed piece of equipment.
Aquarium plants can typically survive in a bag for up to 1-2 days before they need to be planted in an aquarium to ensure their health and growth.
