How many fish can you have in a tank?

Question

How many fish can you have in a tank, how many per gallon, etc?

Answer 1

Depends on what type and size of fish. Keep in mind more fish require more care and filtration. If you are thinking of small Tetra then you could have alot in a small tank, they are tiny. If you are thinking of a catfish or a cichlids, then only a few is adviseable in a large tank.

Answer 2

There are soo many factors to consider when deciding how many fish are good for a tank. You need to consider the size of the tank, the size of the fish. are they aggressive or peaceful? are they fat bodied fish or thin fish? do they produce a lot of waste or just a little? Do they need schools or are they better off alone? Are there any plants in the tank? how much filtration is there? how far are you willing to go to keep the tank healthy? what kind of foods do the fish eat? are they fast moving fish that are aggressive eaters, or are they slow fish that need some time to get to the food and eat it? are the fish sensitive or hardy?

That's just a few of the things to consider. I have not even scraped the tip of the iceberg yet.

try joining a site dedicated to fish, that would be your best bet for setting up a successful aquarium. as for how many fish, it really depends on the fish. some may be really small but like to school and should be keep in groups, others start small but get huge, others are small but will attack all the other fish. before you buy any fish have your tank set up, decide what you want it to look like and then do a lot of research on the fish you're thinking of getting to decide if they will be suitable for your tank.

Answer 4

typically, in small fish a one inch per gallon rule can be applied. however, if stocking african cichlids, overcrowding the fish tends to span out the aggression and one particular fish isnt always the one who gets picked on. Then, when you get to bigger fish, such as oscars, you need to account for the sheer mass of the fish, not just its length. as you move onto bigger and bigger fish, not only does the length greatly increase but so does their girth, or width.

Another factor in how many fish per tank, is just what kind of fish you keep, like goldfish are incredibly messy fish and a 55 gallon tank should only have 3-4 goldfish in it, as well as your tank maintenance schedule and filtration strength.

Answer 5

It depends on what kind or type of fish you are going to keep and how big is your tank. If you are going to keep goldfish then they need atleast 10 gal of water per fish. If you are going to keep guppies then, in 10 gal tank u can keep 8 adult guppies. If you are going to keep tropical angelfish (not saltwater angel) then they need 5 gal of water per fish. Likewise there are different needs for different fish.

Answer 6

Well it figures out to one inch of fish to one gallon of water but take out for other things put in the tank. Stone on the bottom and anything on top of the stones,they all take up space and the fish have less but a tank isn't a tank without them

Answer 7

Depends on the size of the tank, and the size of the fish...2nd is it to be fresh or salt water ? 3rd are you mixing prey with predator fish ?[ they need room to hide] 4th if you have both genders you have to consider room for any possible offspring........now a terrarium that another story

Answer 8

it really all depends on what kind of fish and how big the tank

Answer 9

As many as the big one in the tank can eat.

Answer 10

One inch of fish for every gallon of the tank.

1and1/2 inch is even better
