So because I was naive (and I may even go so far as to say I am a hypocrite and a bad pet owner) and I did no research before acquiring my first Betta, and my first fish for that matter, I got him a tank that's much too small. Currently, he is in a 1 gallon tank with a filter and no heater.
My research on this site says that a 5 gal is the standard for 1 Betta, but I am absolutely stretched thin as far as space in my room. I have decided that a good compromise will be a 3 gallon tank. Because he seems to be doing so well in his 1 gal, I feel that he will have a happy life in a 3 gallon. I just have a few questions.
1.) When I bought my current tank (an Aqueon Minibow 1 gal.) it came with a small whisper filter. Will this filter be too small for a 3 gallon?
2.) Do I have to cycle a 3 gallon tank? I do plan on keeping live plants in the tank when I learn more about them, but I am relatively unfamiliar with cycling other than the fact that I know how to do water testing.
3.) I have a preset heater to put in the tank. It is supposed to work for tanks 2-5 gallons so it should be fine, right?
4.) How often and in what quantities should I do water changes?
5.) (This is more of a general newbie fishkeeping question) I realize that suring 100% tank changes, gravel can be taken out of the tank and rinsed with hot water in a strainer to remove waste. I also have a siphon vacuum for cleaning the gravel, but my question is is there ever a time when you must get rid of the gravel and put all new gravel in the tank?
6.) Do Bettas need an airstone?
That's it for now. I don't have the tank yet and would like more information so I can plan how much I really need to spend. I am already super bummed that I wasted my money on a tank too small to keep any fish happy.
Please, any help would be much appreciated.
