Notes on raising Crowned Dogheads

1. Raising Crowned Dogheads requires a large water tank. Its requirements for the water environment are not strict. The water quality is slightly acidic to slightly alkaline, and the temperature is 24°C~28°C. However, it requires water with high dissolved oxygen, and filtration or oxygenation equipment must be ensured.

2. In terms of feed, Crown Doghead is the same as other fish, but it must be live food, and it must be live food that is jumping around. In order to maintain the hardness of the teeth of the crown fish, calcium supplements are needed. Therefore, the diet of the crown fish must have more shrimps, snails and clams than other freshwater puffers in order to maintain a good balance.

3. There is always a lot of shell residue left in the breeding environment of crown doghead fish, which needs to be cleaned up in time. This prevents the food from spoiling and producing bacteria, which may cause the dog's head to become sick.
