125 gallons is the perfect size for most fish keepers (and for most fish too). It provides your fishy friend with enough room to stay happy and healthy, and it doesn’t take up too much room in your home (which is always a good thing). We compiled the following list of 125 gallon fish tanks and aquariums by reading reviews, comparing prices and even giving them a test for ourselves in a few cases. The list might be pretty short (125 is quite a specific size for a tank after all), but hopefully you find our list useful.
