Yes you do need a filter in your fish tank ifyou don't the tank will build up dirt and the fish will die. Also when you get a fish tank you need to clean it out then fill it with water then put the filter in and wait 24 hours. This helps to ensure that the tank is somewhat stable before adding fish.

What should your fish be in?

If the fish is a coldwater species like a Goldfish it should really be in a pond. If the fish is tropical then it should be in an Aquarium. The size of the aquarium depends on the size and quantity of fish you wish to keep. The basic rule for keeping any fish healthy is "1 inch of fish needs at least 1 gallon of water , a cycled filter running full time and a 50% water change every week."


Do tiger fish need air filter?

ALL FISH NEED THEIR WATER FILTERED. A cycled filter removes Ammonia. All fish produce Ammonia and that poison will kill them if it is not removed from their water. The basic rules for successful fish keeping are as follows. 1 inch of fish needs at least 1 gallon of water :- Every tank must have a permanently running 'cycled' filter. Every tank must have at least 50% of its water replaced every week. Keep to the above rules and your fish stand a chance of surviving. Fail to keep them and I can guarantee that your fish will get sick and die way before they should.
