Can you mix fish with your week old fry?

* Size and Strength: Adult fish are significantly larger and stronger than week-old fry. This means they could easily injure or even eat the fry.

* Dietary Needs: Adult fish and fry have different nutritional needs. Feeding an adult diet to fry could cause digestive problems.

* Competition: Adult fish will compete with fry for food and space, potentially leaving the fry with insufficient resources.

* Stress: The presence of larger fish can cause significant stress to fry, hindering their growth and development.

What to do instead:

* Keep fry separate: The best option is to keep the fry in a separate tank or breeding box. This provides a safe and controlled environment for their growth.

* Gradually introduce: If you must introduce fry to an existing tank, do so gradually. Start with a small group of fry and closely monitor their behavior.

* Choose compatible species: If you plan to keep fry and larger fish together, carefully choose compatible species. Some larger fish are known to be peaceful and tolerant of smaller fish.

Remember, the safety and well-being of your fry should be your top priority. By providing them with a dedicated space and proper care, you can ensure their healthy growth and development.
