Lobsters

10 species

Lobsters are fascinating marine invertebrates that bring a unique aesthetic and behavior to saltwater aquariums. Known for their elongated bodies and muscular tails, lobsters belong to the order Decapoda and are closely related to shrimp and crabs. Their exoskeletons are hard and segmented, providing both protection and support, and they have large, powerful claws used for defense and manipulating food. Lobsters are primarily nocturnal and tend to hide in crevices or burrows during the day, becoming more active at night to forage for food. This behavior makes them interesting yet elusive inhabitants of a reef tank.

In captivity, lobsters require a well-established tank with plenty of hiding spots created by live rock or artificial structures. They are generally hardy but need stable water conditions. A tank size of at least 120 liter (30 gallons) is recommended to provide adequate space for movement and growth. Lobsters are omnivorous and will eat a variety of foods, including meaty foods, algae, and detritus, making them effective scavengers that help keep the tank clean.

However, there are some important considerations to keep in mind. Lobsters can be territorial and may become aggressive towards other tank inhabitants, particularly smaller fish and invertebrates. It's crucial to research the specific species of lobster you plan to keep, as some are more aggressive than others. Additionally, lobsters are known escape artists, so a secure lid on the aquarium is essential to prevent them from climbing out. With proper care and attention, lobsters can be a captivating addition to a saltwater aquarium, offering both visual appeal and ecological benefits.
