what type of fish don't need a filter

The common fish species that are suitable for life in an aquarium without a filter are: Bettas, Guppies, White Clouds, and a few others, sometimes referred to as “aquarium fish”. Bettas are the most common aquarium fish, but they are not the only ones.

Do betta fish need a filter?

To stop a build up of ammonia, nitrites, and nitrates is the most important reason you’re going to need a betta tank filter. Bad news for your betta will come when any of these build up too much in your tank. Your betta’s immune system will be weakened by Ammonia. Nitrites can also be a problem, especially if you have too many of them in the tank.

The best bettas to keep in a tank are those that have been raised on a diet that is high in protein and low in carbohydrates. These are the ones that are most likely to be able to handle a high protein diet and a low carbohydrate diet.

You’ll also want to make sure that the food you are feeding them is a good source of vitamins and minerals, as well as good for the health of the fish. A good rule of thumb to remember is that a fish that eats a lot of high-protein foods will have a higher chance of developing a health problem than one that doesn’t eat that much of that type of food.

What kind of fish can go in a 1 gallon tank?

For a one-gallon tank, you should go with the ones that grow up to 1.5 inches like Neon Tetras, Cardinal Tetras, Flame Tetras, and Ember Tetras. You should keep at least three or four of them in your tank because they’re active.

What is the easiest fish to keep alive?

These creatures are easy to take care of and tend to have low maintenance needs. Some of the easiest fish to take care of in an aquarium are guppies, zebrafish, goldfish, mollies, neon tetras, betta fish, and suckerfish. Guppies are a good choice if you are looking for an easy-to-care-of aquarium fish.

They are also a great choice for beginners because they can be kept in a relatively small aquarium and will not require a lot of attention from the aquarist. However, they do need to be fed regularly to maintain their health and well-being.

Do shrimps need a filter?

Even though it is technically possible to keep red cherry shrimp in an aquarium without a filter, it is still considered best practice to run a shrimp-only tank with a filter, even if it is just a small sponge filter. The water in the shrimp tank is cleaner and healthier because of the filters.

Red cherry shrimp can be kept in a variety of tank sizes, from small to large. They are very easy to care for and will thrive in almost any tank. Red cherry shrimps are a great addition to any aquascape.

Is it OK to use tap water for betta fish?

If you don’t treat the tap water before you introduce it to your aquarium, it will kill your betta. It’s important to read the label carefully because water can vary in density, acidity, minerals, and other factors.

If you’re not sure what type of water you have in your tank, check with your local fish store to see if they have a water test kit that will tell you if your water is suitable for bettas. If you can’t find a kit, you may need to buy a new water filter.

You may also want to consider buying an aquarium water softener, which will help keep the water in the tank as clean as possible.

What fish can I keep in a 2 gallon tank?

Bettas and angelfish are two of the most popular fish in a small tank. Neon tetras, guppies, zebra danios, cherry barbs, otocinclus catfish, oscar cichlids, and other small fish are also available.

If you have a large aquarium, you may want to consider adding a few more fish to the tank, such as an albino fish or a fish with a different color pattern. This will allow you to keep a variety of different fish species in the same tank.
