Betta
Betta splendens
Check BettaThe Betta, also known as the Siamese Fighting Fish, is celebrated for its spectacular flowing fins and bold personality. Males are territorial toward other males but can coexist with peaceful tankmates in a well-planted aquarium. Bettas breathe atmospheric air through a labyrinth organ, so they appreciate calm surface water and access to the top of the tank.

Accessories
Seachem Prime Water Conditioner
The essential dechlorinator for Betta water changes. In addition to removing chlorine and chloramine, Prime temporarily detoxifies ammonia and nitrite — critical in the small tanks Bettas are often kept in where ammonia spikes happen fast.
Filters
Aquarium Co-Op Small Sponge Filter
A gentle, low-flow sponge filter — the gold standard for Betta tanks. Powered by an air pump, it creates almost no current while providing excellent biological filtration. The soft sponge doubles as a surface for Bettas to rest against. Far safer than HOB filters whose intake can injure delicate fins.
Food
Hikari Betta Bio-Gold Pellets
Purpose-built baby pellets for Betta fish. The protein-rich formula with astaxanthin and spirulina promotes brilliant color and fin development. Semi-floating pellets encourage Bettas to feed at their preferred surface level, and the small size means zero wasted food.
Fluval Bug Bites Betta Formula
Insect-based micro granules made with Black Soldier Fly larvae — the closest commercially available approximation to the insects Bettas hunt in the wild. Slow-sinking format mimics natural hunting behavior. Rich in protein with zero fillers.
Omega One Freeze Dried Bloodworms
Premium freeze-dried bloodworms that serve as an irresistible protein-rich treat for Betta fish. Offering them a few times per week provides behavioral enrichment alongside nutrition. Soak briefly in tank water before feeding to aid digestion.
