If you are going with freshwater tropical, it you could add 55 inches of fish. Goldfish, on the other hand need 2-3 gallons per inch, about 22 inches of goldfish.
Technically, a 2 gallon tank for one Cory cat, 4 gallon tank for two Cory cats, and so on. The rule is one gallon per one inch of fish and Cory cats can grow to two inches, although the bigger tank the better. I would DEFINITELY not recommend a 2 gallon tank with one Cory cat. They like to be in groups and will be happier and healthier.
The size of the tank has no effect on how often the fish should be fed. All fish should be fed at least twice daily but only as much as they can eat in 15 minutes. The size of the tank does have an effect on how many fish it will hold. A 10 gallon tank holds that amount when filled to the brim. Under normal conditions it will never be that full so it will only contain about 8.5 gallons. The maximum amount of fish you could hold in there, if you have a permanently running cycled filter and change 50% of the water every week is about 8 inches of fish. Definately no more than that.
You could put a beta in a 100 gallon aquarium and it would do just fine, so long as it had floating plants to give it safe harbor and quiet places to build it's bubble nests. Beta's don't like a lot of current in the water and they love to hang out near the surface of the tank.

The maximum is about 1 inch of fish per gallon of water for most aquariums.1"fish=1gallon2"fish=2gallons3"fish=3gallonsso on but I usually put 1 gallon at the end when I'm done putting fishI have 11 fish in a 25 gallon tank so they have a lot of room but it looks crowdedif you want a lot go high even if you like 10 fish 20 gallon tank you'll end up adding a fish here and there some die then you by more i started with a bunch and ended up with 11. it varies
It can't be done. Goldies get huge unless they are the facy kind. Try a pond or get five in a thirty gallon.
Depends on the size of the fish, but no more than a total of 17 inches of fish. 1 inch of fish per gallon of water.
The rule of thumb is usually a gallon per fish, so six gallons would be good. If the fish are on the large side (like a goldfish), then a seven gallon tank would be ideal.
In that 150 gallon fish tank try to put fish and maintain it
A betta fish would be much more suited to a 1 gallon tank than a 'variety'. You shouldn't keep much more than one fish per gallon anyway.
A small fish bowl is bad for any fish. You need minimal 5 gallon for a single betta. You need minimal 20~30 gallon for a single fancy goldfish, 40~55 gallon for a single common goldfish. Because fish produce ammonia and it is toxic to themselves. Goldfish has such large body mass, so they produce enormous amount of ammonia. You must have a good filter system, and do a nitrogen cycle first before adding any fish at all.
A 10 gallon fish tank is available for purchase from a number of retailers. Such retailers include any local pet and fish stores, such as Petsmart. Ten gallon fish tanks are also available online from Amazon.
