Diet
Betta splendens is a carnivore that eats insects, insect larvae and other small aquatic invertebrates.
Community Compatibility
Suitable tankmates include peaceful, non-fin-nipping species such as small rasboras, kuhli loaches and Corydoras, although individual temperament varies and males should not be housed together.
Good to Know
Betta splendens is known as the Siamese fighting fish because males can be highly territorial and were historically bred for combat in Thailand.
Gender Differences
Males usually have longer, more elaborate fins and brighter colours, while females are generally shorter-finned with a rounder body and may show an ovipositor spot.
