I have a 70 liter, over filtered tank that is home to 5 cory's, 4 Cardinal's, 3 Oto's and one female betta.

She gets fed blood worms, the Cardinals have the tropical flakes, Oto's have their algae and the cory's have their tablets/whatever falls to the bottom.

My girl doesn't like the flakes. Period.

Are these freeze-dried blood worms (by tetra) healthy enough for her?

Or should I consider finding another type of flake food that might be better for her?
