Genus

Common name: Berthella Sea Slugs

Scientific name: Berthella

Berthella is a genus of sea slugs, specifically within the family Pleurobranchidae. These mollusks are part of the order Nudibranchia, known for their often striking appearance and lack of a shell in adult form. Berthella species are not as colorful as many other nudibranchs, typically displaying more subdued tones. They are interesting to hobbyists due to their unique body shapes and behaviors. In the aquarium, they require stable water conditions and a diet that includes sponges, which they naturally feed on. It's important to note that they may not be suitable for reef tanks with a diverse range of invertebrates, as they can potentially harm other tank inhabitants.
