Overview
What to know before you buy.
The Dolabella Sea Hare, or Wedge Sea Slug, is a legendary algae-eater, particularly effective against hair algae. It is a large, mottled green-and-brown slug with a soft, lumpy body. This invertebrate is an eating machine, capable of clearing a tank of algae in a short time. However, this is also its weakness; it will quickly starve to death once the algae is gone, and it rarely accepts supplemental foods. It is completely reef-safe. A fascinating defense mechanism is its ability to release a cloud of purple ink when stressed, similar to an octopus, which can be toxic in a closed system.

Water parameters
Keep pH 8.1–8.4 and 24–28°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.

Behaviour
Dolabella Sea Hare is generally peaceful. Observe during feeding and at lights-out for true temperament.
Tankmates
Pair with similarly sized peaceful tankmates in invertebrates. Avoid fin-nippers or species that outgrow this fish.
Breeding
Breeding notes for Dolabella Sea Hare vary by line and water chemistry — ask your local shop about proven pairs in SA.
Keeping invertebrates?
