The general rule is 1 inch of fish per gallon of water at full stocking levels. So that would be 36 very small 1" fish, or 15 or so 2" fish. Make sure you stock the aquarium slowly, over a number of months.

The 1 inch rule is an old rule of thumb that is not useful to say the least. It depends on species, different fish will have a different impact on the system's bioload. some fish natural produce more waster than others. to simply say a 36 gallon aquarium will be able to hold a 30 inch Arowana is just not practical. generally, small schooling fish such as barbs and tetras can be stocked at higher densities. larger aquatic predators such as Oscars or arowana should be kept in fewer quantities. Think more about the bioload and what the filtration can handle

How many fish can you put in your 186 gallon tank?

It is generally recommended to have 1 inch of fish per gallon of water. So in a 186-gallon tank, you could have approximately 186 inches of fish. However, it's important to consider the specific needs and behaviors of the fish species you choose to ensure they have enough space to thrive.


How many fish can you put in a 2 gallon aquarium?

It really depends on the kind and size of the fish. A single betta (Siamese fighter fish) is probably your best bet, because they aren't that messy, don't need a lot of room, and can breath air. Goldfish, on the other hand, grow very large and are very messy. You could probably fit one or two small feeders for now, but not for very long at all, and you'd have to clean the tank pretty often. Another good choice would be a pair of guppies or platys. Be careful, though, they can also be a bit messy, and they tend to breed like rabbits. Basically, just do some research on the fish before you buy them. A baby angelfish the size of a dime will be alright for a little while, but he'll grow to a good 6 inches before long.


Can you put a 55 gallon aquarium on a non load bearing wall?

It is generally safe to put a 55-gallon aquarium on a non-load bearing wall, as long as the wall is well-supported and in good condition. However, it's important to verify that the wall can handle the weight of the aquarium and water. You may want to consult with a professional to assess the wall's strength and stability.

How many gallon fish tank should you get for your 3 fish?

Depends on the kind and size of the fish. You should also take in to consideration how large they will get at adulthood. A good rule of thumb to go by is 1 gallon of water for every 1 inch of fish. So for example: 3 2" fish should be in at least 6 gallons of water. To be safe I would put them in a 10 gallon aquarium.

Depends on whether or not you have aeration (an air pump). If no aeration, then you shouldn't put more than 2-3 fish "inches" (total inches of fish) in the aquarium. If you do have aeration going, then you can double this amount and have up to 6 inches of fish.
