This calculator uses "surface area" to determine fish stock levels rather than gallons or litres. This is better than a calculator that uses volume alone, such as the common how many fish per gallon rule. (Reference: The Complete Aquarium by Peter W. Scott.) 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. NOTE: Calculations assume the use of an air stone or a filter that disturbs the surface. Adding more air stones will not increase the number of fish your tank will support. Not all fish are alike in their oxygen needs. Slender fish such as tetras or danios use less oxygen than full-bodied fish such as goldfish or oscars. 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. 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. Most fish when purchased are juvenile and much smaller than their full-grown size. fish tanks for sale in knoxville tnFor example, a Red Tail Shark may be two inches in the pet store, but may become five inches within a year! fish tank for sale in peterboroughBe certain to research how big your fish will grow, and use that full-grown value to calculate how many inches of fish your tank will support.fish tanks for sale in lanarkshire

The fish stocking results assume a properly maintained aquarium. This means regular partial water changes and cleaning, adequate filtration, monitored water chemistry, etc. If these conditions can not be met, then the proper number of fish in the aquarium is zero. Fish species characteristics and individual temperaments supersede this stocking guideline. new fish tank show on tvFish that are particularly large, long or active will need dimensions than allow them the physical space they need to be healthy. new fish tank 3 daysFor example, oscars, a popular pet store fish, produce a a great deal of waste and so need more volume than this surface-area might suggest. new fish tank show on tvAggressive fish may need more space for their size (for their tank-mates to stay out of their way.)

Schooling fish will need a minimum number to exhibit shoaling behavior or even thrive. This capacity calculation is only a beginning; research your choices for all the factors that should be considered. Snails, shrimp and plants do not count. In normal populations or typical small sizes, invertebrate bio-load is small, and both invertebrates and plants serve to recycle fish byproducts. Of course, large specimens in a marine tank, for example, should be counted as fish. Add new stock slowly! Your tank may support this many ultimately, but don't stock them all at once! Stock a few fish at a time, a week or more a part, to give the aquarium residents time to adjust and the biological waste processing bacteria time to expand to meet the new demand. Too many fish, even the "right" fish, can overload the natural bacteria that need time to become established. Read more about this on our cycling page. How about a hexagon aquarium?

I need to drill 2 holes in it. Is it tempered glass or not? Thank you The bottom panel is tempered. Any drilling voids all warranty on it. BREX Are the 56 gallon column aquarium being discontinued? I am unable to locate it with stand. No, it is not discontinued. We do not sell it as an ensemble with a stand. They are sold separately through local fish stores. BREX I bought a 150 gal tank a few years ago from Petsmart, and I broke the plastic middle support beam on the top frame while moving. I wanted to know if you can sell a new top frame for the tank so I can replace it. The dimensions are 48in x 24 in. Frames can be special ordered in some cases, through local fish stores, but not large chain stores like Petsmart.

We do not encourage replacing frames because it is not an easy job, and puts a lot of strain on the sealant. It also voids the warranty because of the risk to the sealant. It is considered safer to replace the tank. BREX Ok so I went to the petland on 174 next to me that I was told to go from ya to get a 125 gallon reef ready aquarium from but they told me they don't sell tanks with sumps inside of them so how would I go about get a tank from ya We do not sell direct at all. A 125 gallon reef ready tank will not come with the sump, you will need to buy the sump separately and plumb it into the tank. The tank will simply have corner overflows. You will also need a utility pump. BREX I would like to replace a 60 gallon rectangle glass aquarium that I got with a heartland stand. so far nobody will sell me just the aquarium. Can you please help. So you have the tank, but want to replace it with the same one? We also make a 55 that fits that stand. The 55 isn't quite as tall, but is the same length and width.
