If the feeding is not clean or the water quality changes, and the new fish tank and supporting facilities are not disinfected, eggs and parasites will enter the fish tank and invade the fish, causing friction between the fish and the fish tank. Generally, this kind of fish doesn't like swimming. The surface of the fish is dull, the body color is dim, there is no transparency, the expression is dull, and it hides in the corner of the fish tank with fins shaking.

Maintenance precautions:

1, when raising Hu, you should first prepare a big fish tank and fill it with trapped water in advance. Feed can be algae or carnivorous insects, which can be fed three times a day. Be careful not to put too much feed to prevent water quality from deteriorating due to feed accumulation.

2. Hu is very demanding on water quality. The owner should clean the fish tank regularly and change the water frequently, but it is recommended to leave a little old water at a time to prevent the fish from getting used to it. When changing water, tap water should not be used directly, and it should be dried for 2 days to decompose chlorine gas. If possible, you can install a filter in the fish tank to remove dirt.

Hu is an alien fish, and his mood is relatively docile. Mixed culture with fierce fish is not recommended to avoid injury. The owner should try to keep the water temperature of the fish tank consistent at ordinary times, without drastic changes, and generally maintain it between 20-30℃.
