Small Fish Tanks

This webpage will focus on small fish tanks under 10 gallons.  You might be thinking “Hey, the cheap fish tank page had four small aquariums under 10 gallons!” and you are correct, but this is a huge category and there are many, many options in this size range.  So here are EIGHT more nice small fish tanks under 10 gallons.  Keep in mind that a small fish tank isn’t truly appropriate for goldfish as is often believed.  However, they are great for betta fish, or a few tetras, mollies, danios, or other small freshwater fish.  We wouldn’t normally recommend a saltwater tank less than 10 gallons as the small fish tank size can make keeping the water parameters specific to saltwater more difficult.
