1. Environment: Puffer fish has relatively high requirements on the environment. When raising artificially, it is necessary to keep the water temperature above 20 ℃. They come from temperate, tropical and subtropical regions, so they need higher temperatures. The water quality of seawater puffer fish is relatively fresh when it comes to origin. When it is cultured artificially, it is necessary to keep the water quality of their life clean, which can reduce their discomfort.

2. Space: Although puffer fish is not very large, the breeding density should not be too high. When cultured artificially, it is necessary to keep the living space of puffer fish sufficient, so that they can develop their body shape better.

3. Oxygen: Puffer fish does not have a high demand for oxygen, and it does not need to be deliberately oxygenated under normal circumstances. However, in summer, when the temperature is on the high side, the oxygen in the water will decrease. At this time, it is necessary to install an oxygen pump to keep the dissolved oxygen in the water sufficient.

puffer fish prefer animal feed. When artificially cultured, they need to be fed more live bait or freeze-dried feed to ensure their adequate nutrition. Foods suitable for puffer fish are shellfish, snails, shrimps, fish and so on. If there is not enough food, you can also feed some freeze-dried shrimps and frozen fish. Juvenile puffer fish are sensitive and easily frightened. After being frightened, the eating of puffer fish will also be affected. When cultured artificially, it is necessary to keep the surrounding environment quiet to avoid them being frightened.
