The bigger the tank the better. For most common freshwater fish, it is recommended that you have a 10-gallon tank per fish, with the dimensions of 22” x 12” x 13.5”. For most common saltwater fish, it is recommended that you have a 30-gallon tank per fish, with the dimensions of 36″ x 18″ x 12″.

Aquarium Dimensions: Sizes Under 100 Gallons

For a beginner, 5 gallons is the minimum recommended tank size, though a 20-gallon tank or larger is even better.

Aquariums up to 55 gallons can be placed almost anywhere without much worry at all. Many tanks larger than 55 gallons and no more than 125 gallons will be okay, if they are placed in a good structural location and your floor framing is free from significant defects.

How Much Does a 100 Gallon Fish Tank Weigh. If you have a glass 100 gallon fish tank that measures 60” x 18” x 20” then it will weigh approximately 831 pounds when it is completely filled with freshwater. The same 100 gallon glass fish tank will weigh 850 pounds if it is filled with saltwater.

Thicker Walls and Better Materials Lead to Higher Prices And so this is why aquariums can be—and usually are—pricey. Large aquariums are thicker and made of more expensive material than smaller tanks in order to withstand the pressure.

You might want to hide this one from your significant other or accountant, but according to a story on SFGate.com, scuba diving and aquariums are listed as two of the more expensive hobbies to have.

Fish. Unless you’re looking to go the exotic route, with ornate saltwater species and plants, the cheapest pet to own is probably a fish. The set-up will definitely be the most expensive part, with a basic 20-gallon tank costing close to $200, complete with lighting, filters, air pumps and gravel.

If you want to keep tropical freshwater varieties, or just your hardy little friend, Goldy, then costs will vary accordingly. You can, generally, start up a good freshwater system for between $300-$500. Fish and food will be extra, but these cost far less than saltwater. Ongoing costs are also much less.

You need not fret if a fish dies, immediately replace the fish with another one, as it is believed that your problems tend to reduce with the death of every fish. It is strictly advised that the fish feed should be planned and fed by only one person. The tank or the bowl should be cleaned regularly.

Regular cleaning may cost around $85, but that depends on the size of your tank. Some aquarium maintenance services charge $1 dollar per gallon, so cost widely varies.
