The reasons why the Assam Milk Tea Brontosaurus does not eat food may be as follows:

1. Not adaptable to the new environment: This requires waiting patiently until it is familiar with the environment. Can eat now.

2. The food is unpalatable: You can try feeding some fresh live food or shrimp that the Brontosaurus likes to eat.

3. Inappropriate temperature: Especially in cold weather, the water temperature needs to be controlled between 22°C and 28°C. This water temperature is more suitable for the growth of Apatosaurus.

If these basic problems are eliminated, then you need to consider whether the fish is sick. If the fish is sick, it needs to be isolated and treated in time.
