### How many fish can I put in my tank?

This method for estimating how many fish a tank can support is superior to the traditional a “how many fish per gallon” or “per litre” rule of thumb, such as “one inch of fish per gallon” or “one centimeter of fish per litre”.

### How many fish per gallon of water?

In reality, the water volume is often ten to fifteen percent less than the size of the tank. While the one-inch of fish per gallon rule is a reasonable yardstick, it has its flaws. To be safe, with big-bodied fish like goldfish and cichlids, one-inch of fish per two gallons of water is a safer rule to go by.

### What determines the number of fish in an aquarium?

The surface of your aquarium is where oxygen diffuses into the water. The more surface area, the more easily oxygen diffuses, and therefore the more fish your aquarium will support. For example, a tall, narrow 29 gallon aquarium cannot maintain as many fish as a standard rectangular 29 gallon tank because less water surface contacts air.

### How much surface area do I need for my fish?

The calculator reflects this by providing two extremes. For slender fish, we use the value of 12 square inches of surface per length-inch of fish (or 30 sq cm/1 cm of fish) For full-bodied fish, we use the value of 20 square inches per inch (50 sq cm/1 cm) of fish. Cold water tanks and marine tanks have higher surface requirements.

### What is fish count and why is it important?

Fish count is an important consideration related to aquarium size. Keeping fish count proportionate to the aquarium size, volume of the water, aquarium dimensions and the types of fish being kept is necessary to avoid overstocking your aquarium.

### How many fish can you keep in an aquarium?

The best way to work out how many fish you can keep in your tank is to use an aquarium stocking calculator. Simply insert the details about your fish tank shape and dimensions, together with information about the fish species you plan on keeping, and the calculator will tell you how many fish you can fit in your aquarium.

### How to determine fish count in aquarium?

Determining fish count needs to include any snails, clams, shrimp, crabs or anything other living organism in an aquarium. All life in an aquarium takes from the water and adds to the bio-load. So fish count is really not just about counting fish.

### Does aquarium water surface area affect fish count?

The more aquarium water contacts air, the greater the rate of gas exchange in the tank. Therefore, lower aquarium water surface area means a lower fish count per gallon. Filtration, aeration and aquarium water surface agitation are other important factors in determining fish count.

### How does surface area affect fish in aquariums?

The more surface area, the more easily oxygen diffuses, and therefore the more fish your aquarium will support. For example, a tall, narrow 29 gallon aquarium cannot maintain as many fish as a standard rectangular 29 gallon tank because less water surface contacts air.

### How much surface area do fish need in a tank?

Cold water tanks and marine tanks have higher surface requirements. Cold water fish need a minimum of 30 inches of surface area per inch of fish (76 sq cm/1cm); marine fish need a minimum of 48 inches of surface area per inch of fish (122 sq cm/1cm). The stocking results apply to the full, adult size of the fish.

### What is the surface area of a fish?

For slender fish, we use the value of 12 square inches of surface per length-inch of fish (or 30 sq cm/1 cm of fish) For full-bodied fish, we use the value of 20 square inches per inch (50 sq cm/1 cm) of fish.

### How much space do fish need per gallon?

For starters, the one inch per gallon rule (or 1cm per 2L) only works for tropical freshwater fish; cold and marine fish need more space. Also, tanks are often not filled to capacity; space at the top and displacement by decorations and gravel varies from tank to tank.

### How many inches of fish are in a 20 inch tank?

If wide-bodied fish are kept in the tank, the calculation should be changed to one inch of fish for every twenty inches of surface area. Like the one-inch rule, the surface area rule isn’t perfect. Its primary advantage is that it takes into account unusually shaped aquariums.

### Is a 5 gallon tank big enough for a fish tank?

A 5-gallon tank is the smallest you can have for successful fishkeeping. The environment and water quality in very small aquariums quickly become unstable, jeopardizing the health of your fish, and even the smallest fishes need space to swim around.

### Can cichlids live in a 20 gallon tank?

In fact, there are many types of cichlids out there such as: angelfish, dwarf cichlids, ram cichlids, discus fish, oscar fish, etc. From the ennumarated fish species, only ram and dwarf cichlids should be kept in 20 gallon aquariums.

### Can you put a fish in a 20 gallon tank?

Although a 20-gallon tank does offer a fair amount of space, whatever species you choose, the fish must have plenty of room to swim and turn around. For example, extremely active, large fish such as Roseline Sharks need a tank that allows them adequate space to shoal and moves around freely.

### What can I Feed my Goldfish in a 20 gallon tank?

They’ll eat leftover fish food that falls to the bottom of the tank, but you should include some sinking pellets to be sure they get enough to eat. They are shoaling fish, and should be kept in groups of at least six. For a 20-gallon tank you might consider a few different varieties.
