because they haven't adapted to this environment. Submarines are difficult to raise, demanding the environment, and eating things is also very troublesome:

water temperature is 24~28 degrees

water quality is

weakly alkaline water, soda (semi-seawater), and the specific gravity formula of soda is as follows.

assuming that the average length of the boat is x cm, the required specific gravity is 1.X ..

For example, a boat with a length of 5 cm needs a specific gravity of 1.5.

The salt for soda mixing should be natural seawater salt, and ordinary iodine-containing salt should not be used.

Fish tank space

It is best to set up fish tanks according to 1-15 liters of water for each boat.

High-density breeding may cause water quality deterioration and bring unnecessary territorial struggle.

food

shrimp, snails, snails, red worms and small fish are hard to accept artificial pellet feed.

polyculture

it is not suitable for polyculture with other fishes, shrimps and snails.

1. If you want to keep small boats for a long time, you must use soda water, so you can't mix them with freshwater ornamental fish.

2. The dinghy is aggressive and may attack other fish. In order to avoid tragedy, don't mix the dinghy with other fish.
