I have many guppy fry and I want them to grow. They are 2 months old and are still the same size as they were when they were born. I really want them to grow and I know that Brine Shrimp will help them grow but is this right? Brine Shrimp are still living creatures and shouldn't be killed.

What other options do I have? I already feed them powder fish food.

Thx
