The New Fluval Betta kit is specifically designed to replicate the tropical habitats of this popular fish species, and comes equipped with multistage diffused filtration, soft LED lighting and a convenient pre-set heater - all tailor-made for Betta splendens. Appropriately sized at 2.6 US Gal (10 L), the Fluval Betta Aquarium Kit is large enough to permit ample swimming space and allow the hobbyist to easily maintain optimal water conditions, yet small enough to keep control of water movement, filtration and heating.
