Is 2 gallons enough for a betta?

Yes, it is the practical minimum for one betta, but a 5-gallon tank is easier to keep stable. Plan on weekly partial water changes and no tankmates beyond maybe a snail.

Does it come with a heater?

No. The kit covers filtration and lighting only. Bettas and other tropical fish need a small adjustable heater, and a 2-gallon tank needs one rated for that volume.

Is the tank glass or plastic?

Product listings conflict, describing it as both acrylic and glass. Ask the seller to confirm before you buy, since glass and acrylic clean and scratch differently.

What can I keep in it besides fish?

Shrimp, snails and small crayfish suit it better than most fish. Lizards, spiders and seahorses do not belong in a 2-gallon water tank despite what some listings suggest.

How hard is setup and maintenance?

Setup is simple: rinse, add dechlorinated water, run the filter and cycle the tank before adding fish. Maintenance means weekly partial water changes and filter media rinses, more often than on a larger tank.

Our take on the 2-Gallon Acrylic Fish Tank with Filtration and Lighting

The Freesea TF-250 is a small starter aquarium kit that bundles a tank, filtration and lighting in one box. At 2 gallons it is a desktop or children's-room tank, sized for a betta, a few shrimp or snails, not for goldfish or a community of larger fish. The kit competes with other all-in-one nano tanks on convenience rather than capacity: you get the light and filter without buying them separately, but 2 gallons leaves little room for error on water quality. Listings describe it inconsistently as both plastic and glass, so confirm the material before buying.
