Genus
Common name: Heart Urchins
Scientific name: Lovenia
Lovenia is a genus of heart urchins, a group of burrowing sea urchins found in sandy substrates. They are characterized by their heart-shaped test and spines that aid in burrowing. In the aquarium, they can be beneficial by aerating and turning over the substrate, which helps prevent the buildup of harmful gases and detritus. They are generally peaceful and can coexist with a variety of tank mates. However, care should be taken to ensure that the substrate is suitable for their burrowing behavior and that they are not outcompeted for food by more aggressive feeders.
