FAQs About Aquariums Up to 10 Gallons

Even before you add any gravel or accessories, a 10 gallon fish tank filled with water will weigh more than 75 pounds. To protect your fish friends and their habitat, always place the aquarium on a sturdy surface that can support its weight—preferably an aquarium stand specifically designed to hold its specific size.

A 5 gallon tank is perfect for some small freshwater species like bettas, GloFish, mollies and guppies. Avoid overcrowding and problems with incompatible or aggressive species by consulting a Petco aquatic specialist to help determine which species are best suited for your aquarium.

A 5 gallon tank that’s filled with water, gravel and décor will weigh approximately 8 to 10 pounds per gallon—upwards of 50 pounds total. Choose a sturdy surface or purpose-built stand to support your aquarium and keep it from getting knocked over.

That depends on your tank’s exact dimensions, as well as your personal preferences (and those of your fish). For planning purposes, you’ll need roughly 1 to 2 pounds of gravel per gallon of water to achieve a 1- to 2-inch base.

With a 10 gallon tank, you can choose a variety of some small freshwater community species, like dwarf cichlids, tetras, rasboras, cory cats, danios or loaches. The greater numbers and species of fish often bring a greater risk of overcrowding and aggressive behaviors. To strike the right balance, talk to an aquatic specialist at Petco for stocking suggestions.
