Do i need a filter for my betta fish?

Answer 1

In the wild, bettas usually live in small bodies of dirty or crowded water. They have developed an organ known as a 'labyrinth' that allows them to breathe atmospheric air. A betta can survive for a short time in a damp tissue because of this. They do not need their water aerated or kept crystal clear the way most fish do, and dislike the water movement created by filters. However, this does NOT mean they can be kept in small vases like many people do. The absolute minimum size container for a betta is 1/2 gallon (2 litres) and this will need a 100% water change every two days. Make sure the water is treated and the same temperature as the old water. Bettas also prefer decorations such as gravel and plastic plants, which make them feel more at home. In larger tanks, very low-flow filters (preferably bubblers) can be used but are not required.

It is a misconception that betta fish need to be kept in a small tank. Pet shops often keep the fish in small tanks as it would take up to much room to put each of them in their own separate larger tank (they can't be housed together as they will fight). When you take your betta home though a larger tank will allow him or her to swim around and explore. I have a beta in a 7 inches high, 12 inches long, 6.5 inches wide tank with a few real and artificial plants for him and a cute little castle that he can swim through. He loves to swim around and play and explore. Bettas that are kept in tiny bowls become quiet and docile as they have no room to swim and play. Get a tank around the size of mine and watch how entertaining it is to see him explore!

Beta splendens actually prefer filtered water. They evolved a labyrinth organ and belong to the Anabantoidei family. Basically they can absorb oxygen from the surface where the oxygen exchange occurs for all fresh/salt water. So while normal fish would die in bowls or small enclosures from lack of oxygen and poor water conditions, these fish can survive and adapt to the low oxygen levels that occur when there is no or little surface agitation, but they would still benefit from low ammonia, nitrite and nitrate levels.. Even in the lily pools they have live sand and plants to help filtrate there water.. So the answer is yes, Betta would absolutely love filtered water

All fish need a filter running because all fish create ammonia in their water. The filter uses bacteria to convert this poisonous ammonia into relatively harmless Nitrate. Betta splendens evolved in the paddy fields and tiny pools of the Asian tropical jungles where low oxygen levels was a common problem. These fish and the whole of the Gourami family evolved to be able to obtain air by gulping at the surface. They did not evolve in high Ammonia (poisoned) water so they are still burned by ammonia and their gills and fins etc are still damaged by it.

The basic rules for successfull fishkeeping are. 1 inch of fish needs at least 1 gallon of water.(A Betta is a 3 inch fish so it needs at least 3 gallons of water. Not a 'nominal' 3 gallon tank which will only hold around 2.5 gallons in use) :- Every tank must have a permanently running 'cycled' filter. Every tank must have at least 50% of its water replaced every week. If you follow the above rules your fish will stand a reasonable chance of surviving. If you don't, then I can guarantee that your fish will be constantly getting sick and will die much sooner than it should. A Betta is a tropical fish and should be kept at over 75F but under 80F.

Answer 4

of course you do you need the fish to have WATER because every fish in the world needs water so the betta fish needs it to,to live so the betta fish does need a FILTER

Answer 5

yes but they don't realy need it
