Why fiddler crabs molt

Author Note: Many Fiddler Crabs will lose a limb at some point in their life. If this happens, the crab should regrow a new limb when they molt. Fiddler Crabs are natural-born scavengers. When they eat, these crabs will use their claws to put substrate in their mouth. They then sift through the substrate and eat the organic matter. This includes algae, fungus, and tiny insects. Dry foods are readily available and a viable option for Fiddler Crabs as well. The food is formulated to provide all of the nutrients the crabs need.

Just drop some pellets or flakes into the water and watch the crabs find them. If you want to supplement the dry food, you can provide plankton, brine shrimp, seaweed, blanched zucchini, and bloodworms. Feed your crabs once a day. If there are any leftover foods the next day, remove them to prevent the water quality from deteriorating. Fiddler Crabs never get boring, which is one of the reasons they make such great pets!. These critters are very active and can scurry across the sand very quickly.

You might see the crabs spitting out tiny little sand balls as they search for food. Sometimes, males can get a bit territorial. They can also get into disputes over a female. If push comes to shove, they could end up fighting and losing a limb or two. Author Note : One cool behavioral quirk you can observe is waving!

Fiddler Crabs will wave their big claw to communicate. This behavior alerts others of their presence. Fiddler Crabs do best in small groups of at least two. As for other tank mates, you have limited options. Not too many fish will survive in the brackish waters Fiddler Crabs need. Furthermore, these crabs will try to catch the fish for food! Other invertebrates, such as snails or shrimp , might work. However, the risk of the crab hunting them down is still present.

Simply put, Fiddler Crabs do best in a single-species tank. My husband then placed him back into the tank and the darned thing is on its back again. He can and has reached the top of the tank for air. He can either climb the air tube and hang from the top of the plastic hood, or there is a rock he can climb and be flat and be able to stick out of the water. He thinks there is a small line down the middle of the belly that he has seen move a little.

Is it possible he is molting? We hope it isn't dying Thanks in advance for your help!

Gel packs and cooler packs beat ice hands down. Why Fiddler Crabs Molt When fiddler crabs grow too large for their current shell, they will molt and form a new larger one, giving them the space to expand. Fiddlers can also use a molt to get rid of harmful toxins, which concentrate in the chitin, or regrow lost limbs. If a fiddler loses a claw, they will regrow a new one.

If a male loses its big claw, the small claw will grow to become the big claw. Many lose legs, for the same reasons they lose claws. The good news is that crab legs regenerate in the same fashion as claws, forming as limb buds just prior to a molting cycle. Alternatively, use a partly filled fish tank and place large rocks into the water that the crabs can use to climb out of the water. Feed your fiddlers.

Place the crabs in a cooler or a bushel basket that is layered with ice packs and covered with a moist burlap sack. You want to maintain a dark, cool and moist environment to keep the crabs alive. Just keep in mind that the crabs need air too. Do not put them in a sealed container or a cooler with the lid shut. You can keep the crabs in a cooler, just remember to keep the lid cracked open so they can get air.

They are very active during the day and return to their burrows at night and during high tide, plugging the entrance with mud or sand. While people typically buy hermit crabs —which aren't technically crabs —as pets , actual saltwater or freshwater crabs can also make great companions.

Pet crabs require a large tank that's kept at the right temperature and partially filled with sand and either fresh or brackish slightly salty water.
