* Water: Blue mussels need to live in saltwater with a salinity of around 35 ppt. The water should also be well-oxygenated and have a pH of around 8.2.
* Temperature: Blue mussels can tolerate a wide range of temperatures, but they do best in water between 68-75°F.
* Food: Blue mussels are filter feeders and they will eat algae, plankton, and other small organisms in the water. You can also feed them commercially-prepared foods for saltwater mollusks.
* Substrate: Blue mussels need a substrate to attach themselves to. This can be anything from rocks to shells to even pieces of PVC pipe.
* Lighting: Blue mussels do not require a lot of light, but they will do best if they have some light for at least part of the day.
* Filtration: A good filtration system is essential for keeping blue mussels healthy. The filter should be able to remove both solid and dissolved waste from the water.
* Water changes: Regular water changes are also important for keeping blue mussels healthy. You should change about 10% of the water in the aquarium every week.
By following these tips, you can help your blue mussels thrive in your aquarium.
