1, coral sand or shell sand is the best fish tank.
2. It doesn't matter how much salt you want, but you must have it, and you don't have to keep a constant value.
3, puffer fish also like to avoid, it is best to provide a nest or a big leaf of fake aquatic plants, such as water banyan.
4. The filter must be powerful, because if you eat more, you will eat more meat.
5. The food likes shrimp and snail best. Watch out for snails. It is best to take out the meat and feed it. According to my observation, the technology of eating snails in submarines is not as good as chocolate dolls, and blood worms are also a good choice. Pure lean meat is also ok. Never bring fat, bread bugs are ok.
6. If you don't eat, you may not adapt to the environment. No feeding is required within 1 week after purchase. 1 After a week, meat food will be tentatively put in, and it will usually be eaten in one to two weeks.
