How many fish can i take home?

One of the most common but most difficult questions we receive is “How many fish can I put in a 10 gallon tank? How about a 20 gallon tank? 55 gallons? As you can guess, there are an infinite number of possible fish combinations for each size of aquarium that we can recommend. To keep things simple, let's first understand the three factors that will most affect fish population levels, and then let's discuss our general guidelines for introducing the right amount of fish into your aquarium. In the same way, the tank must handle all the fish waste, especially if it is a large one. In many cases, you can measure the number of fish based on gallons of water.

For example, there is a modern rule of 1 fish per 1 gallon. However, as many aquarium lovers would say, it hasn't been perfect. I've been raising fish for more than 30 years and I currently have 4 different aquariums, it's an addiction. Despite all this enthusiasm, many people reach a point of confusion when deciding how many fish per gallon are best for their aquarium.

There is no adequate science that dictates the perfect ratio between the number of fish and the amount of water. Instead, you must consider many factors, such as the accessories you place, the possibility of fish getting sick and, of course, the types of fish you would like to have in space. You may need to add lots of ornaments and plants (which also reduces space for swimming) to break the line of sight so that weaker fish can easily escape and hide from the dominant ones. The best thing would be to judge the area based on what the fish look like when you buy them and put them in the tank.

That's why we've prepared a guide to how many fish per gallon in your aquarium is the best option, answering some common questions. Under the water surface area rule, the tank can be stocked with one inch of fish for every twelve square inches of surface area. However, if you increase capacity and choose fish that generate a lot of waste over time, specific filtration options are needed. This general rule applies primarily to small community fish that are approximately 1 to 3 inches (2 to 7 cm) in size.

You'll also change and become a more experienced fish farmer over time, able to safely maintain a fish tank with more stocks without harming its residents. Many beginning aquarists like to buy large quantities of fish at a time, but it's always best to substock the aquarium at first and get more fish later if possible.
