A “5 gallon bucket” can only be assumed to be five gallons, give-or-take a gallon – unless you measure it.

45 gallons

1,155 cubic inches

The volume of a five-gallon bucket can be expressed in cubic inches or cubic feet. One U.S. liquid gallon is equal to 0.134 cubic feet, which means a five-gallon bucket is equal to 0.670 cubic feet. A five-gallon bucket is equal to 1,155 cubic inches.

For example, to find out how many liters there are in 5 gallons, multiply 5 by 3.785411784, that makes 18.9270589 liters in 5 gallons. How many liters in 1/2 gallon? There are 1.89271 liters in 1/2 gallon.

A 5 gallon fish tank is a fantastic solution to this. They will often come in dimensions of around 16″ x 8″ x 10″ and can fit on any desktop or surface. Yet still they are big enough to be fitted with a filter and heater safely which most fish need to thrive and have happy lives.

Best Fish For a 5 Gallon Tank (And Small Tank Benefits)

• Betta Fish (Betta splendens)
• Guppies (Poecilia reticulata)
• Cherry Shrimp (Neocaridina davidi)
• Mollies (Poecilia latipinna/Poecilia sphenops)
• Pygmy Corydoras (Corydoras pygmaeus)
• Neon Tetras (Paracheirodon innesi)
• Harlequin Rasbora (Rasbora heteromorpha)

A 36 gallon bowfront will house a total of 12 inches of large-bodied fish quite easily. If you choose a species of fish that remains under 6 inches you will have just enough room to keep two fish.

Common Fish Tank Sizes and Characteristics

Ideally, however, a 75-gallon tank is best for one adult Oscar and, if you plan to keep more than one, you will need a tank at least 100 gallons in capacity. In addition to supplying your Oscars with the right size tank, you also need to cultivate the right tank conditions.

On average, your tank will measure 65″ L x 30″ W x 24″ H. How heavy is a 200 gallon fish tank? A gallon of water weighs approximately 8 lbs. Multiply this by 200 and the water weight alone of your tank is 1600 lbs.

Propane prices vary by location. A propane refill will cost between $3 and $5 per gallon, or about $500 for a 100-gallon tank….Propane Tank Prices.

75 Gallon Aquarium Dimensions The typical size of a 75 gallon aquarium is 48″ x 18″ x 24″. However, this can vary slightly from tank to tank. A tank of this size will weigh a lot more than smaller tanks, especially when filled. Expect your tank to be around 140lbs when empty and 850lbs when filled.

Generally, most 90-gallon tanks are priced around $100, but they can also go up to $1600 if they ship with a stand and useful gadgets. You can also purchase a second-hand model that costs $100-$200. However, the risks for purchasing second-hand aquariums are high.

It’s the size. If you get 90 Neon Tetra, their bio-load might be as much as 9 Congo Tetra. In a fully cycled 90 gallon tank with sufficient bio-filters, you can have 90 fish if they are as small as Neon Tetra.

In a 90 gallon tank, and with the current fish, I think adding 3-4 medium sized fish (4-5 in) would be appropriate. There are a lot of factors to decide though.

Below is a small overview of species that you can keep in the 90-120 gal aquarium.

• Discus and Scalare.
• Cichlids.
• Common tetra species: neon tetras or Rummy-nose tetra.
• Different catfish.
• Loaches: Black-lined Loach or dwarf loaches.
• rainbow fish.
• Barbs: Fiveband barbs, tiger barbs or Odessa barbs.
• gourami.

The rule of 1 fish per gallon is surely applicable but only to a certain extent. The species of the fish needs to be primarily considered. Since it is a 100 gallon tank, you can also apply the concept of different zones. You can have maximum variety by choosing according to the zones occupied by the fishes in the tank.

About 8 would be great in a 90 gallon. They are very easy and hearty fish.

One of the easiest ways to get an idea of how many fish your tank can accommodate is by using a Rule of Thumb of 1 inch of fish per gallon. This means that if your tank has a capacity of 80 gallons, you will theoretically be able to accommodate 80″ of fish.

Also, i would say that a 150, complete with sand, rocks, filters, and a stand is too heavy for a floor that isn’t supported with concrete or extra beams. A floor must be able to hold 40 pounds per square foot in order to be safe for a single family residence.

Best Fish for 1 Gallon Tanks

1. Guppies. Guppies are one species of fish that you can keep in a small tank.
2. Bettas. Bettas are one of the hardiest species of fishes around.
3. Neon Tetras.
4. Endlers Live Bearers.
5. Zebra Danios.
6. White Cloud Minnows.
7. Dwarf Spotted Danios.

For a 3.5 gallon, the best option for me would probably be a betta. These look well on their own. Aside from bettas, you can put any live bearing fish, such as guppies, or a shrimp. Just place one fish, or else it would get overcrowded.
