How Many Saltwater Fish Can You Put in a 125 Gallon Tank?

Assuming you are referring to a marine/saltwater setup, the rule of thumb is 1″ of fish per gallon. So a 125 gallon tank could theoretically hold 12.5″ or about 10-11 adult fish. However, it’s always best to err on the side of caution when stocking a new tank and start with fewer fish. You can always add more later as your tank matures and becomes more stable.

How Much Does a 125 Gallon Saltwater Tank Weigh?

A 125 gallon saltwater tank can weigh anywhere from 600 to 1000 pounds when full. The weight will depend on the type of saltwater, the amount of live rock and sand, and the size and weight of the fish and other invertebrates in the tank. A heavier 125 gallon tank can easily top 1000 pounds.

What is a Good Size for a Saltwater Tank?

Aquariums come in all shapes and sizes, so it’s really up to the individual when it comes to deciding on the perfect size for their home. That being said, there are a few things to consider when choosing an appropriate aquarium size for saltwater fish. The first thing to think about is the type of fish you want to keep.

Saltwater fish come in all shapes and sizes, from tiny clownfish to huge groupers, so you’ll need to choose an aquarium that can accommodate your desired fish. Another factor to consider is how many fish you want to keep. It’s important not to overcrowd your aquarium, as this can lead to stress and disease amongst your fish population.

A good rule of thumb is one gallon of water per one inch of fish (excluding the tail). So, if you want to keep a school of six clownfish, you’ll need a 36-gallon tank. Lastly, think about where you’ll be placing your aquarium.

Make sure you have enough space in your home for the tank, plus any additional equipment like filters and pumps. A good size for a saltwater tank really depends on the individual’s needs and preferences, but taking these factors into consideration will help you make the best decision for your setup.

How Many Saltwater Fish Can Be in a 100 Gallon Tank?

Assuming you are talking about a standard 100 gallon saltwater aquarium, the short answer is that you can keep up to fish in a 100 gallon tank. This number will change if your aquarium has live rock or other decorations that take up space. The long answer is a bit more complicated.

How many fish you can keep in a 100 gallon aquarium depends on the size of the fish, whether they are reef-safe, what kind of filtration system you have and how often you do water changes.

For example, if you want to keep large fish like clownfish or angelfish, you will be limited to 2-3 fish per 100 gallons. If you want to keep smaller fish like gobies or chromis, you could easily keep 10-20+ fish in a 100 gallon aquarium.

It is also important to note that not all saltwater fish are reef safe. Some species of triggerfish and wrasses are known for nipping at corals and other invertebrates. If you plan on keeping any coral in your aquarium, it is best to avoid these fishes altogether.

Finally, it is important to have a good filtration system and perform regular water changes (weekly for small tanks, bi-weekly for medium tanks and monthly for large tanks). Otherwise, your ammonia and nitrite levels will quickly rise and poison your fish.



This person has a 125 gallon saltwater fish tank and is wondering what to do with all the extra space. They are considering adding more fish, coral, or both. However, they are also worried about overstocking their tank.
