Is a 20 gallon tank big enough to keep 1 Oscar or a jack dempsey or a green terror?

Im not sure about the green terror but with the Oscar and maybe jack dempsey as long as your fish isn't full grown (10-14 inches) then it will probably be fine

What semi-aggressive fish would be good for a tall 40 gallon tank?
Jack Dempsey or Tiger Oscar
Can an Oscar and a jack dempsey interbreed?
yes
What size tank should you have for two oscar's and a few jack dempsey's?
Oscars get extremely large so I would suggest something at least 180 gallon, but 250-300 would be better.
Can a Common Pleco and an Oscar live in the same 75 gallon tank?
An Oscar needs at least 55 gallons, and common plecos can grow to a foot long - you must make sure you have enough filtration for this
Can a Oscar live in a 56 gallon?
yes
Shall you keep all Oscar fish in one tank?
If the tank is large enough. For rearing young Oscars a 50 gallon tank is about right for 5 fish.
What are some aggressive fish for a 75 gallon tank?
You could have an Oscar tank containing 1 oscar (can reach over a foot) with a convict cichlid. Convicts grow to about 6 inches in length and are still tough enough if they are getting bullied by the Oscar, but generally small enough as not to be a large threat to the oscar. Silver Dollars are also a good choice to go with an Oscar. Instead of a convict you could have a Firemouth cichlid. I have kept these and they will reach about 6 inches in length, but are still big enough to hold their own against an Oscar. If you want a really agressive fish you could get a Midas cichlid. These extremely agressive fish can reach a foot in length, but you would want to give him the whole tank to himself because he would attack any other fish with him. You could try some smaller cichlids with him, but its hot or miss whether he will accept them. Another agressive fish would be the Jack Dempsey. These guys grow about 8 to 10 inches and can be agressive with other fish in the tank, the same goes with the Green Terror cichlid. Basically cichlids are the way to go with agressive fish, so do some research on any one in particular you find interesting. Good Luck!
What size filter do you need for one large Oscar in a 75 gallon tank?
A 75 gallon tank is not large enough to house an Oscar in the long term, however if the situation is temporary a mid to large sized canister filter or very large hang on the back filter would be nessesary. I recommend an Eheim 2217 or Aquaclear 110.
How many gallons do you need for 1 Oscar?
A well set up and properly filtered 30 gallon tank would accommodate 1 oscar. It is recommended to have up to 55 gallon tank as they can grow up to 18 inches.
Can an Oscar fish live in a ten gallon tank?
A small oscar can live in a 10 gallon for a short period of time. However, oscars are fast growers and can reach lengths larger than a foot so a larger tank would be required soon.
Who said i am not young enough to know everything?
Well, it can either be J.M. Barrie, or Oscar Wilde. But i fully believe that it is Oscar Wilde as I am doing a quote by Wilde and it is I am not young enough to know everything.
Can an Oscar fish be in a 40 gallon tank?
No. An Oscar needs a minimum of 75 gallons with an extra 20-30 gallons per each added Oscar. Oscars grow very large and are predatory. Please read up on them before you even think about getting one.
