Alevin

Newborn fish.

Alevin is a term used to describe a young fish which is still in the growth and development phase. Dolds are generally very small and can be difficult to distinguish from adults.

Dolds generally arise from eggs laid by adult fish, but some species can also give birth to living fry. Dolds generally need a lot of care and food to grow and develop properly, and they are often very vulnerable to predators and diseases.

It is important to take care of fry in an aquarium, as they are often very sensitive to temperature and water quality changes. Dolds need quality food and sufficient quantity to develop properly. It is also important to keep the aquarium clean and regularly change water to avoid diseases.

It is recommended to put the fry in a separate bac so that they can grow up and develop safely. Dolds can be fed with food specially designed for fry, such as pellets or glitter. It is also possible to give them living foods, such as artemias or daphnia.

You have to be patient with the fry, because it may take them for several months, even several years, to reach their adult size. However, taking care of them properly, you can help your fry to grow and become beautiful healthy adult fish.
