A very small one but only if you can fit a working filter to it. There are a couple of basic rules to follow if you with to keep fish alive and well. The rules are :- 1 inch of fish needs a minimum of 1 gallon of water. :- Every container with living fish needs a permanently running, cycled filter to convert poisonous ammonia to harmless nitrate. :- Every tank needs to have at least 50% of its water changed every week. If you follow those basic rules you should be successfull. If you choose to ignore those rules the experience of millions of aquarists proves that your fish will be constantly getting sick and dying on you.

You can put any kind of fish in the tank if they are not overcrowded and the fish all get along. A good rule of how many fish to put in a tank is one gallon per inch of fish.

1 gallon tank what type of fish can you put in it?

A 1 gallon tank could have one betta fish, but you will need to be diligent about changing the water on a regular basis. The smallest tank that should be used, even for a betta, is a 2.5 gallon tank as it at least gives the fish swimming room.
