When filled with water, aquariums can be incredibly heavy. As beginners aquarists, it is easy to underestimate the weight of tanks. My first fish tank measured 10 gallons in size. It’s fitting that I write about the weight of a 10-gallon fish aquarium.

Don’t worry! This article will not be limited to 10 gallons. We’ll cover much more.

10-Gallon Fish Tank Weight

When empty, a 10-gallon aquarium (or leader) weighs around 11 lbs. It weighs approximately 111 lbs when full.

A 10-gallon tank has a standard dimension of 16″ x 8″, x 10″ (LxWxH).

Let’s now look at the dimensions and weight of standard aquarium sizes. These figures are only applicable to glass aquariums. Acrylic aquariums are usually lighter than aquariums made of glass.

Does A 10-Gallon Aquarium Need A Stand?

Although 10-gallon aquariums can be quite small, they need sturdy supports. An adequately-made cabinet will suffice most of the time. Avoid cabinets or stands that are smaller than the tank’s width. This will cause extra stress and leaks.

You should also inspect the wood used in the construction of the cabinet. This is because certain woods can swell when they are wet, which can cause damage to the overall support.

Woods such as maple, cedar, and spruce will shrink or expand when exposed to water. Mahogany, walnut and oak are exceptional at resisting shrinkage and warping.

Fish For A 10-Gallon Fish Tank

A 10-gallon tank can be used to stock beautiful, vibrant fish if you have chosen the right species. But smaller tanks can be temperamental than larger ones. There is no room for error.

You should select small, non-hyperactive and certainly non-aggressive fish.

Here are our top picks for fish that will fit in a 10-gallon aquarium. These fish can be kept as an individual or part of a group. They are also very hardy and rarely require any special care.

• Platies (2-3 inches)
• Swordtails (4-5 inches)
• Fancy Guppies (3-5 Inches)
• Betta Fish (2-4 inches)
• Neon Tetras (1.5-2 inches)
• Cory Catfish (2-4 inches)
• Zebra Danios (1.5-2 inches)
• Dwarf Gouramis (3-3.5 inches)
• Otocinclus Catfish (1.5-2 inches)
• Ghost Shrimps (1.5-3 inches)

• Cherry Shrimps (1.5-2 Inches)

How Many Fish Can Go Inside A 10-Gallon Tank?

It is subjective. Start by adding one small fish to every gallon of water. You can add them one at a time for several weeks. After the tank has matured, and you feel confident in your abilities, you can add two neon-tetra-sized fish to each gallon.

Final Words: 10 Gallon Fish Tank Weight

Here’s a quick recap for you. When empty, a 10-gallon fish tank is just 11 lbs. When it is filled, its weight rises by 10 times to reach 111 lbs.

Even though it is a small aquarium, it needs to be supported by a sturdy and durable surface. A sturdy, well-built cabinet will suffice.

Small tanks can be easy to maintain. This is far from the truth. You are much less likely to make rookie mistakes in small tanks. They can easily become polluted and have a tendency to fluctuate in water parameters. Be aware of what you are signing up for.
