I know we have some fish lovers on here and I'm hoping some of you are betta people. I am planning on adding a betta to the family in the near future. I want to house him in a 5 gallon tank (have not bought the tank yet) with a filter and a heater. I would also like to get him live plants to enrich his environment a bit. I have been reading up but have a few questions... -How often will I need to change the water/clean the tank? -When I do change the water, how much should come out at a time? -What equipment is best for this? -What do i do with the fish while I change the water? -How often should I change the filter?
