well, this could really depend on what kind of fish and what kind of filter you have in there.

Not many. The only thing I would put in a tank that size is 2 bettas with a divider.

i agree about the betta lol i use the 1 inch of fully grown fish per gallon rule but the rule can be bent depending on type of fish and filter like lookoutworld said.

Sooo, following the 1 inch rule...You could have a 12 inch fish in a 12G tank? I think no...

LOL, I just think it depends on the bio-load. If you have a 10 gallon tank, and 10, 1-inch goldfish (DO NOT DO THIS) then you would have a ton of waste. I never go by the 1 inch rule, because it's not correct....sometimes. Just make sure all the fish are happy, get enough food, and don't fight with eachother.

as a general rule if it's a fish that gets no bigger than 1 inch it can count for 1/2 gallon. if it's a fish that gets bigger than 5 inches than it counts for 1 1/2 gallon. so lets say you have a 5 gallon tank and you want guppies. since guppies get to be about an inch you can put 10 guppies in with no problem. if you wanted guppies and a goldfish you would account the goldfish gets as big as 6-7 inches so you can get 1 gold fish and 7 guppies. this is of course an example and i'm sure the measurements of guppies or gold fish i mentioned are not exact but at least you can follow the concept. hope this helps.

Yes, but some fish are super messy, like goldfish and oscars.

yea i think the only expection to the 1 inch per gallon rule are goldfish and really messy fish those are never good on a small tank, you may want to stick with some of the smaller schooling fish like neon tetras and other small tetra fish. also you may want to consider checking out an african dwarf frog. those you can keep about 2 per gallon and they are great pets.

It may be a better approach to ask how few fish you can put in a given aquarium. A small capacity tank like five gallons will develop problems much faster than a large aquarium. If some uneaten food makes a bit of ammonia, it will be more concentrated as part of five gallons than it will be as part of 20 gallons. If you start with too many fish, you're almost certain to have problems. An under populated aquarium will have fewer problems, and if you keep the fish healthy, they will populate the aquarium soon enough.

+1 for John!
Unless you purposely buy fish that are on the "difficult to breed" list like I do hahaa!

to anserew the ? 1 male betta 1-2 snails 2-4 shrimp is really gud for a 5 gallon. or 2 female bettas 1-3 shrimp 1 snail. or a nice schol of neon tetras of like maby 6-8 1 snail and maby 2 shrimp. when i was 6 all the way till i was 14 a 5 gallon is all i had i think i had like 5 5 gallon tanks the bigger tanks where my moms and i had sum goldfish and sum other in her tanks. but for the 6 5 gallons i hade my one had 1 male betta 2 live plants 6 shrimp 2 snails and even a very small pleco. # 2 had 2 female bettas 1 snails. # 3 had 8 neon tetras 1 snail 4 shrimp. # 4 had 3 platies and a small pleco. # 5 had 4 kuhli louches wit 1 snail. # 6 had 2 mollies 1 snail. u can have a quit a few dif small fish. it is alot better to have a 10 gallon plus. also the filter does have alot to do with it. if ur filter isint strong enuf and is kinda week then mainly bettas is all. when i had these tanks i was to yung to relize i was slitly over stocking my tanks. but i had a very gud filter for all of them.

If an aquarium has a near maximum biological load, it also has a very small tolerance for errors.

yes it does. the best thing for a 5 gallon is 1 male betta and shrimp and snails. but there r also lots of other things that could work in there.

The 1" of fish per gallon is "Very" rule of thumb....(it can be bent).
The way to apply this rule to messy fish (and this is the "actual" rule) is 1 cubic inch of fish per gallon.

However applying this "rule" in the linear fashion of 1" per gallon is advised for beginners.
This is because using the cubic rule for small fish like neon tetras you will have a figuring like this.

1 1/2" X 1/4" X 1/2" this equals 3/16 (or about 1/5). This will give you 5 fish to 1 gallon.
For a very experienced fish keeper this will be reasonable, but as John Arthur points out, this will cause bigger problems for smaller aquariums. AND YOU CAN NOT PUT 5 NEONS IN A 1 GALLON TANK!!!!!

......

However the other end of this scale would be something like my saratoga (which is 20&quot.

20" X 4" X 1.5" this will mean such a fish is best kept in (around) a 120 gallon tank....this is a very reasonable suggestion.

''''''

I hope this can go some way to clearing up any complexity about keeping a 6" angel in a 6" tank.

E.g. an angel fish is 6" X 6" X 1/2" this means 18 gallons for such a fish. Here a bit of common sense is needed as an angelfish is not square, nor a cube and there is allowence for the shape of the fish and the fact that it is a shaoling species (unlike a saratoga).

However if we apply the 1 linear inch of fish per gallon "rule" then we must be aware that it is not advised to keep this species in less than a 20 gallon tank. However we can then add 1 new fish for every next 6 gallons to create a shoal.
This minimun of 20 gallons can obviously be arrived at by using the cubic inch rule, but to only add 1 fish per 18-20 gallon is far from reasonable.

This is where both the linear and cubic rules are relevant. Also both are only rule of thumb and will come back to experience, tank maintenance, filtration and the type of fish.

Hope this goes some way to clearing this up...I doubt it....LOL

btw since you can keep 1 x 20" saratoga in 120gallons, if anyone can keep 2 in 240 gallons, let me know (please don't try this!!).

It's not OK unless the goldfish are very small. Over crowding can cause aggressive behavior, and it will produce lots of toxic ammonia. The likely result is sick fish.

Water quality may be improved somewhat if you change about 20 percent of it every day and use a full function tap water conditioner to treat the replacement water. Goldfish are usually big eaters, and they grow to be very large. The nitrogen cycle in a five gallon aquarium will not be able to handle the biological load produced by four goldfish.

Brittney: Think about one male betta for the five gallon tank. A pair of guppies may be fine for a while, but they will make lots of little guppies. If you load the aquarium to its limit, the fish will likely all get sick for reasons previously mentioned.

Since you are new to the hobby, you may want to take a conservative approach. Here are a few pointers:
http://www.myaquariumclub.com/your-first-aquarium-how- to-make-it-successful-564.html

The one inch per gallon rule can be very misleading and often encourages over crowing. That and over feeding are the primary causes of most aquarium failures. A two inch goldfish displaces a lot more water and eats much more food than a two inch guppy.

I hope some of this helps. Please keep us posted.
