Mussels can be kept with fish. Mussels have a wide range of food, to freshwater phytoplankton such as diatoms and nudibranchs, zooplankton such as rotifers and flagellates as the main, other aquatic plants and crustaceans can also feed on the rotting debris. Mussels do not eat small fish. Therefore small fish and mussels are safe to keep together.

To keep mussels, you need to put a layer of sediment on the bottom of the tank for mussels to live in. You can mix it with multiple fish to ensure that the water is not deprived of oxygen.

Mussels habits:

1, habitat

In the natural environment, the mussels generally live in the rivers, lakes, swamps, streams and other muddy, sandy or gravel. Winter and spring cold use of axe feet digging mud Fen, so that part of the mussel body buried in the mud and sand, the front abdominal edge down, the back edge of the dorsal upward; only part of the back edge of the shell for respiration and feeding. When it is hot, most of it is exposed outside the mud.

Toothless mussels generally live in muddy bottom, pH value of 5 to 9 in still water or slow-flowing fertile water.

2, action

clam's ability to act is very weak, when the environment is calm, by the ligament pulling, emblem slightly open double shell, slowly extend the axe foot. General axe feet to the front of the shell out, and fixed on the mud, and then shrink the clam body to move forward. This crawl is very slow, usually only a few centimeters a minute forward. Wherever the mussel body passes through are left a shallow groove.

When the mussel encounters hostiles, the axe foot quickly retracted, the closed-shell muscles at the same time sharp contraction of the double shell tightly closed to defend against external enemies.

3, growth

Clams are dioecious, the reproductive glands are located around the dorsal intestines of the foot, in the form of grapelike glands, the spermathecae are milky white, and the ovaries are yellowish. The reproductive ducts are open, and the genital pores open very small behind and below the renal pores.

The reproductive season of the mussel is usually in summer, and the spermatozoa are fertilized in the gill cavities of the external gills until the hooked larvae are formed. Fertilized eggs are not washed out by the water flow due to the adhesion of the mother, but remain in the gill cavity to develop. Therefore, the gill cavity of the external gill is also known as the nursery sac.
