  • Brine shrimps
  • Blood worms

They can eat frozen or dry foods. 

Feeding routine: You should feed your adult Betta fish twice a day. Also, make sure the water’s surface is unobstructed because Betta fish are surface eaters. 


Betta fish require a clean environment, so they can grow and stay healthy.
