Crabs are not picky eaters. They eat almost everything. Small fish and shrimp are the crabs' favorites. When feeding, they can be separated from feed and bait, such as red worms, fish and shrimp, snails and so on. In the crab tank, the owner can spend some time planting aquatic plants, such as goldfish, bitter greens, water peanuts, duckweed, water lilies, rotifers black algae and so on.
If you can't find small fish and shrimp suitable for it. Sometimes use small earthworms instead. But it's heavy and inhumane for small earthworms. So I suggest we feed shrimp. It is also very tasty. Try to eat as close to it as possible because in my experience they don't see very well. Don't disturb him with food. My baby crabs used to kill each other because they were so small. Now each crab has a broken arm and leg. We must all be kind to animals.
Lastly, crabs are omnivores, but be careful with food. They can't just eat them, they might die. In their natural environment, most are twisted. Mussels also have some food such as small fish and shrimp. If they are not expensive, they are smart enough not to eat some weeds, floating weeds, etc. If they are older, it is recommended to feed them small fish and shrimp. They love them all and at least you can eat them without putting some weeds in them. The best way to feed crabs is to feed them small fish and floating weeds. /feed/5d6034a85edf8db17c23714d47bdbc5d564e7435.jpeg?token=1dab8647d1094a6d3d9f972021552ddd
