1. Lobsters are easily attacked by other lobsters when they shell (because they will smell fishy, and other lobsters will think it is feed and attack him). Note: those who attack lightly will kill those who attack heavily, so I suggest keeping one or two lobsters. 2. I suggest that novices should keep Australian blue lobster (not crystal blue lobster) or freshwater lobster. These two kinds of lobsters are cheap and easy to keep. (If they are magic shrimps, you'd better give up and keep the two kinds I mentioned first and then consider them for about one year, because they are really difficult to keep.). 3. Necessary things for raising lobsters are as follows: 1. Bottom sand: Coral sand is the best bottom sand, which provides the calcium needed for lobster hulling (lobster hulling is easy to fail in case of insufficient calcium intake, which will be ugly), and makes the water quality weak alkaline (lobsters are suitable for weak alkaline water quality) * * * Pumping up&; Filter water: basically, it's not necessary to pump air, but if you have it, it doesn't matter, you must filter water. 2. Shelter: Shelter is very important. When you raise more than 2 (including) lobsters, you must have shelter to avoid being attacked by the same kind when they shell (he will hide in it). 3. Water plants: basically, you don't need water plants, so you use mousse. But in the end, it will be eaten up by lobsters ... 4. Landscaping items: Your tank is so small, you should leave some room for lobsters to move ... 5. Plastic grass clips: Lobsters have a lot of stools and are very long. Grass clips are used to change the water for holding the stools: basically, the number of days to change the water will be determined according to the size of your tank. Tell me how big your tank is and how many to keep first, but if you have a small tank, you will change the water every 2 to 3 days. If you want to feed, you usually choose benthic feed, buy rat fish and so on. Never buy goldfish with sinking type. The sinking speed is very slow. If you are interested, please call me. I know there is a cheap and big bowl of feed. 29-4-17 17:53:28 Supplement: Your blue lobster tank should be at least 1 to 12 inches long ~ ~ Note:-You can't keep two in a thin tank.-Change the water once a week or two regularly.-It's enough to feed once a day.-You need to pay attention to not scaring your parents when changing shells.-Lobsters are best fed at night.-The sand bottom is best. Shrimp falls into the tank-if you don't put the water plants well, you will bite the blue lobster. There are two kinds: American blue crayfish/Australian freshwater blue lobster. The above two kinds are very different and confusing! !

But if the water temperature is too low, I'm not afraid ~ It is recommended that the water temperature be below 3℃ ~ above 3℃: it needs a cooling fan, a water cooler and below 18℃: it needs a warm pipe-lobster food, lobster (dry) food, red worms, young fish, shrimp larvae (pit shrimp), shrimp (dry) food-brand: Hongjinbao ...
