I am not from Delhi or Mumbai, and yes we have lots of packed fish food available online from china or Japan. I feed my fish mostly packed food, previously I used freeze dried tubifex Worms, had used water quality issue.So, now I am using 'Optimum' brand fish food, and boiled veggie (someone recommended). Just want to know, what others are feeding their fish to keep them healthy and strong. How to grow red wigglers ( Can I grow them in small container) to feed fish? Thank you!
