Just a few questions about betta tank setup?

A 5 gallon is best anything lower can't be heated and is unsuitable for fish as it can not be cycled. A 25watt heater will do and you should also get a low powered filter such as the penn-plax small world filter or corner box filter. The easiest way to establish cycle bacteria would be to use water and filter media from a larger tank and add the fish straight away but you can also do it the conventional 3-6 week way. a href="http://www.tropicalfishcentre.co.uk/Fishlesscycle.htm" rel="nofollow"http://www.tropicalfishcentre.co.uk/Fish…/a
