You have baby fish in your pond should you keep them away from the other goldfish and koi?

It is generally recommended to separate baby fish, often referred to as fry, from adult goldfish and koi for a period of time until they reach a suitable size. There are several reasons why separation may be beneficial:

1. Predation: Adult goldfish and koi can often view fry as a source of food and may prey upon them. Keeping the fry separate minimizes this risk.

2. Competition for food and space: Fry require specialized care and feeding compared to adult fish. They have smaller mouths and different dietary needs. Keeping them separate ensures that they have access to appropriate food and avoid competition with larger, more dominant fish.

3. Disease transmission: Mixing fry with adult fish can increase the risk of disease transmission. Fry have weaker immune systems and may be more susceptible to diseases carried by adult fish. Separation helps prevent the spread of any potential infections.

4. Ease of observation: Keeping fry in a separate tank or enclosure allows for easier monitoring and observation of their growth, behavior, and health. This can be particularly useful for identifying and addressing any issues early on.

The duration of separation will depend on the species and size of the fry. For example, goldfish and koi fry may need to be kept separate for several weeks or even months until they reach a size large enough to hold their own against adult fish. It's important to consult with experienced aquarists or experts to determine the best approach for your specific situation.
