Filter

The filter must not be too strong else our fish will get sucked in. This issue particularly happens with betta fish or baby fish. So, we need to be very careful while deciding the filter. It is certain that fishes are able to successfully survive for a while without a filter.
However, it is always a decent idea to consider tank with filter. If the water is cleaner, the fishes will stay happier inside and will live longer.
What Fishes are Suitable inside a 2 and 2.5 Gallon Tank?

We can consider fish tank that already comes with the lighting system. This is because the built-in lighting could make up the mood for the fish. Also, it will facilitate the growth of plants resembling the actual underwater environment.
Frequency of Cleaning
To guarantee the effective working of our 2 and 2.5 gallon fish tank kits, the cleaning mechanism needs to be considered. Generally, such tanks need to be cleaned at least once every week.
We need to keep in mind that tiny fish tanks should be cleaned much more often than bigger tanks. The fish waste, debris, and other pollutants build up quickly in the smaller tanks. Therefore, they need to be cleaned regularly. We need to aim to clean them once per week and make sure we perform regular water changes.
HOW MANY FISHES FOR 2 AND 2.5 GALLON TANK?

Rember, The reproductive ones like livebearers can cause a further population growth, make sure not to keep them in pair.
SOME STOCKING IDEAS THAT CAN COME IN HANDY.
Regardless of the choices, you are going to be limited to a group of three and a couple more at best. To boost the liveliness of the tank, opt for the choices like cherry shrimps. They are tiny and require no maintenance. The shrimps will make the tank look more alive and provide it with some motion.
Similarly, zebra snails can prove to be the natural cleaners of the tank. They will reduce the amount of debris and waste material in the tub and make the environment more pleasing for the fishes.
