I hate how small they are but if I get a baby fish I want to put one in a 2.5 gal tank until I can upgrade. Now my questions are what kind of heater can you put in a 2.5 gallon tank and can you cycle a 2.5 gallon tank? The one I found comes with a filter so it would be cool to cycle the tank.
If I cycled a tank that small could I clean it only twice a week with 50% water changes? Once a week when fully cycled? Or is twice for a smaller tank still better?
Also could I keep two shrimp and one real plant in there? I was thinking java moss and two shrimp to help keep it clean.
